So , i dry masterbate alot like 3 times atleast Sometimes up to 6 or 7 daily i noticed some very unnoticeable bumps very very small cant even feel them if i wipe over my penis with my finger . They dont hurt or anything . Their is just a wierd tingly feeling like a very mild burn . when i wear underwear . Im going to be honest since i want an answer . My masterbating technique i kinda just rub around the head or like a tickling move . Ive been going through a time where i go on Wearing dirty underwear in which i previously ejaculated in more then once .I know its nasty but it happened im 22. Last time i had sex was a little over a month with an older lady about 39 that just got divorcedci asked her to go get checked for std's she wentband said she was clean. I have small bumps around the head before this that dont bother at all they been there for atleast a year . My uncles are doctors and i dont wanna just go there and humiliate myself. Does anyone have an image of what might caused this
