Im 20 years old, I dont have an STD, and havent had sex since I was 18. Ive always used protection. When I get an erection, there is a snake-like bump under the skin that develops. Sometimes its bigger than other times, and will get bigger after masturbation. I first noticed this about a year ago, but Im starting to date again, and Im very self conscious of this on my penis. Is this dangerous? Should I see my doctor? Thanks!
Hello, Its normal to have larger veins in penis after erection. It's the blood into the penile tissue that causes erection, afterwards blood flow towards heart via veins causing them to look more swollen than usual. Hope I have answered your query. Let me know if I can assist you further.
