A guy who is knowledgeable about penis health knows that penis bumps are a not-uncommon occurrence. But there’s a lot to know about penis bumps, including various causes. The following quiz can help test a man’s knowledge about penis bumps and see what he knows and what he may need to bone up on a little.

The test

- Q: These penis bumps are small and dome-shaped. They tend to be skin-colored or a little lighter than the skin. They appear in one or more rows around the bottom of the head of the penis. They are benign and do not affect a man’s physical sexual performance or indicate the presence of an STI. What are they?

A: Pearly penile papules, medically known as hirsuties papillaris genitalis or hirsuties coronae glandis.

- Q: These visible sebaceous glands are very common and present as painless, raised bumps that tend to be white, pink or red. They are small, generally between 1 mm and 3 mm in diameter, and frequently appear on the balls as well as the penis. They sometimes can occur in the mouth or on the face as well. They are benign and present to physical concern and do not indicate the possibility of an STI. What are they?

A: Fordyce spots.

- Q: The penis bumps associated with this STI start out as a reddish or brownish discoloration on penis skin, and then moves on to groups of round blisters. The blisters contain a fluid that tends to have a light yellow tinge to it. They go away after a few weeks, but the infection that caused them remains. What is the STI that produces these bumps?

A: Herpes type two.

- Q: Human papillomavirus (HPV) often produces bumps that are commonly called by a different name. They are irregular in shape, and the color varies based on skin tone. Most of the time they are painless and often have an appearance reminiscent of a cauliflower. By what name are these bumps usually known?

A: Genital warts.

- Q: True or False. Penis bumps, even benign ones, always interfere with a man’s sexual performance.

A: False. Although some men may feel self-conscious about some penis bumps and may therefore have a psychological reaction that impacts his performance, benign bumps by themselves do not affect a man’s bedtime activities. However, bumps that are infectious can have an impact, either because they may be painful or because a man should refrain from sex until an STI is under control.

- Q: Which one of these potential causes of penis bumps is an STI?

a. Folliculitis

b. Syphilis

c. Lymphoceles

d. Angiokeratomas

A: b. Syphilis.

- Q: A mite causes this skin condition, which often includes a pimple-like rash. It can occur on other parts of the body as well. The mites are spread during skin-to-skin contact, usually during a sexual encounter. What is the name of this condition?

A: Scabies.

Men who did well on this test already know a great deal about penis bumps - and that bodes well for them being aware of basic of overall penis health as well. This includes daily application of a first rate penis health crème (health professionals recommend Man1 Man Oil, which is clinically proven mild and safe for skin) . As many penis bumps occur due to skin issues, choosing a crème that can keep penis skin healthy is key. The most effective choices will contain both a high-end emollient (like Shea butter) and a natural hydrator (like vitamin E). The moisture lock they make helps keep skin well-hydrated. It’s also wise to look for a potent antioxidant among the ingredients. One like alpha lipoic acid will be able to wage war against the free radicals that can cause oxidative stress, which is responsible for significant penis skin damage.
