hi im and 18 year old male and have been in a steady relationship with my girlfriend for 7 months. About 4 months ago i started to get a red bump on the head of my penis, and my thighs, arms, back and butt became very itchy. the bump went aways after about 3-4 weeks of my picking at it, it would scab over and i just would pick the scab off and it would bleed. the bump would go away then another would appear in a different spot (still on the head of the penis). now i also have tiny bumps inbetween my fingers, toes, and on my arms, and some other random spots. i dont know what this is, and im scared it could be and std. the bump on the penis doesnt itchy at all, in fact i cant even tell its there, it is just an embarsing spot that lowers my confidence. Do you think it could have anything to do with my girlfriends birth conrol medicine because these bumps started about the time she got on it.
pleases help me with some kind of answer.
