Improve erection and boost libido: the complete buying guide (2026)

The four most commonly used categories at a glance, including key considerations and recommendations to seek medical advice.

YMYL note: this article is general information, not medical advice. Persistent erection problems or a prolonged low libido require a GP visit. Sources used in this article: Thuisarts.nl, ISSM (International Society for Sexual Medicine), Mayo Clinic.

A cock ring (penis ring) is placed at the base of the penis or around the penis and scrotum, restricting blood from leaving. This can extend the firmness of an existing erection and sometimes give a fuller sensation. A cock ring does not create an erection in the absence of arousal; it is designed to maintain one that already exists.

Types:
- Rigid (metal, hard silicone, hard rubber): maximum effect, but harder to remove if the erection persists. Only suitable when you already know the right size.
- Flexible (softer silicone, TPE): easier to put on and take off; recommended for beginners or when you are still finding your size.
- Vibrating cock ring: combines the ring with a vibrating attachment for extra stimulation of both partners.
- Double ring (penis and scrotum): provides an even more intense effect; requires more experience.

Size: too tight is dangerous; too loose has no effect. Measure the circumference at the base of the penis when flaccid or semi-erect and choose a ring slightly smaller than that circumference.

Safety rules (ISSM and medical literature):
- Wear a cock ring for a maximum of 20-30 minutes.
- Never sleep in one and do not use one during masturbation if there is any chance of falling asleep.
- Remove the ring immediately if you experience pain, tingling, numbness, or if the penis turns cold or blue/purple.
- An erection lasting more than 4 hours is priapism: a medical emergency. Go directly to Accident and Emergency. Priapism can cause permanent damage to erectile tissue if left untreated.
- With cardiovascular conditions or blood thinners: always consult a doctor first.

Topical erection creams and gels are applied directly to the penis. They generally work in two ways:

1. 1Blood flow-supporting (caring effect): Ingredients such as L-arginine, menthol, or certain plant extracts produce a tingling or warming sensation and may temporarily stimulate superficial circulation.
2. 2Numbing (desensitising): Creams containing benzocaine or lidocaine reduce sensitivity in the glans, which may help with premature ejaculation.

What you need to know:
- Topical creams are not PDE5 inhibitors (such as sildenafil/Viagra) and have no proven clinical effectiveness for organic erectile dysfunction.
- Never use a numbing cream if you have any pain concerns; pain is a warning signal.
- Transfer to a partner: during oral sex or penetration, the active ingredient can reach your partner. Use a condom or wash the cream off before penetration.
- Stop use if you experience skin irritation, redness, or a burning sensation.
- Do not use on broken skin or mucous membranes.

Supplements and libido boosters are sold as dietary supplements, not as medicines. This distinction is legally and medically significant:

• They may not make any medicinal claims (EU legislation).
• The effectiveness of most ingredients (such as maca, ginseng, tribulus terrestris, L-arginine, zinc) is limited or not convincingly scientifically proven for erectile dysfunction or libido in people without deficiencies. Effects vary considerably between individuals.
• They are not a replacement for a PDE5 inhibitor (such as sildenafil or tadalafil) or for treatment of an underlying condition.

Safety: interactions with medication
This is the most serious safety risk. Some ingredients in supplements (and certainly recreational drugs such as poppers/amyl nitrite) can dangerously interact with medications containing nitrates (nitroglycerin patches, isosorbide dinitrate for angina). The combination can cause a severe drop in blood pressure. Always consult a doctor or pharmacist if you take any medication, especially heart medication or antihypertensives, before taking a supplement. Never combine recreational drugs (poppers) with erection aids or medications.

When might a supplement be useful?
For mild, situational low libido without an underlying condition, a supplement may play a supportive role (placebo effect and a sense of taking positive action are not excluded). Do not expect spectacular or rapid results.

A vacuum pump (penis pump) draws blood into the penis via negative pressure, after which a cock ring maintains the erection once the pump is removed. This is a clinically proven aid that is also recommended by urologists for men for whom medication does not work or is contraindicated.

For detailed information on how it works, types, how to use it, and safety limits, see the separate guide penispomp kopen.

Key considerations: do not use the pump for too long or with excessive pressure; stop at the first sign of pain or numbness. With cardiovascular conditions, consult a doctor first.

Many people assume that erection problems are purely psychological, but the Mayo Clinic and Thuisarts.nl emphasise that organic causes are just as common:

Physical:
- Cardiovascular disease: reduced blood flow is the most common cause in men over 40. Erection problems can be an early signal of cardiovascular disease.
- Diabetes mellitus: damages nerves and blood vessels.
- Hormonal factors: low testosterone, elevated prolactin.
- Medication: antidepressants (SSRIs), beta-blockers, antiandrogens, and certain antihypertensives can affect erection and libido.
- Obesity, smoking, alcohol: negatively affect blood flow.

Psychological/relational:
- Performance anxiety, stress, depression, relationship difficulties.
- Low self-esteem or a negative body image.

When to see a GP:
For persistent (more than a few weeks) or worsening erection problems or low libido, always see a GP. The doctor can rule out or treat cardiovascular, hormonal, or psychological causes. Thuisarts.nl explicitly states that erection problems in men over 40 can be a cardiovascular risk signal.

Use this decision framework as an initial orientation:

1. 1Are the problems temporary and situational (for example, stress, fatigue, alcohol)? A cock ring or a blood-flow cream can be a useful addition alongside relaxation and a healthy lifestyle.
2. 2Do you want to keep an erection harder or longer? A cock ring is the most direct mechanical aid.
3. 3Is libido reduced without a clear physical complaint? First consider lifestyle factors (sleep, exercise, stress, diet). A supplement can be a complement, but expect limited effects.
4. 4Have the symptoms persisted for more than a few weeks? See a GP. Self-treatment with supplements or aids is not the right approach in that case.
5. 5Are you taking any medication? Always consult a doctor or pharmacist before taking a supplement.

These are the situations where you need to seek medical help immediately or promptly (sources: Thuisarts.nl, ISSM, Mayo Clinic):

• Erection lasting more than 4 hours (priapism): go immediately to Accident and Emergency. Priapism can cause permanent damage to erectile tissue if left untreated.
• Pain, blue or purple discolouration, numbness of the penis during cock ring use: remove the ring immediately and if symptoms persist, call a doctor.
• Persistent or worsening erection problems (more than a few weeks): see a GP. This may be a sign of an underlying cardiovascular condition, diabetes, or hormonal disorder.
• Low libido combined with fatigue, weight changes, or depression: see a GP for hormonal and psychological assessment.
• Side effects or allergic reaction to a cream or supplement: stop use and consult a doctor or pharmacist.
• Combining a supplement with nitrates or heart medication: always consult a pharmacist or doctor first, due to the risk of a serious drop in blood pressure.

Disclaimer: This is general health information, not medical advice; for any symptoms please consult a GP, doctor, or sexual health specialist.

Cock rings are the most direct mechanical aid for maintaining an erection and can be used safely as long as you respect the time limit (20-30 minutes) and know the safety signals. Erection creams provide a temporary circulatory or desensitising effect, but are not a clinical treatment. Supplements are dietary supplements with limited or unproven effectiveness; use them as a complement, not a substitute for medical advice.

For persistent symptoms, a GP is the right first step. For a detailed comparison of vacuum pumps, see the guide penispomp kopen. For a full lubricant overview, see glijmiddel kopen.
