Bump in pubic area close to my penis what could it be ?

There are several possible cuases of skin bumps, both genital and non-genital -- far too many possibilities to even guess without physician exam. If you are sexually active, maybe a genital wart -- excpet that most GWs occur direclty on the genitals, not the pubic area. Most genital area skin problems are not STDs. See a doctor if you remain concerned.

Depends on many things like a boil, bruise, fat pad etc. If it does not go away in a couple of weeks pl see your MD for withot exam exact diagnosis is difficult. Hope you do well
