Hi, I have gotten a total of 5 red spots now I think, they come and go away, Im only 17 and havnt had any sex or anything related, this probaly isnt a std but its kinda freaking me out, I have heard rumors that my brother fools around a lot and has Std's and we share the same bathroom so I dont know.these spots are round and small and redder than my normal skin color, I have gotten them on the head, shaft and testies but I have only gotten 5 so far and they usually go away in a week, and they are painless, any input will be greatly appriciated
