i dont even know how to ask this but i ll try.

i have a bump in a very private place. right at the top just above everything. it was there a while ago and then it went away but now its come back. its like a little hard marble or something under the skin and its sore to touch. god this is so embarassing. ive been tested for std's since the first time it came up so i dont think it can be that. could it be related to maybe my time of the month coming up? or um... its about where theres friction when um... stuff is going on so maybe it could be from that? i would just ignore it but im worried cos i just met someone and there could be questions i cant answer.

im so embarassed. does anyone have any ideas what it could be or what i can do about it? ive been using anti-septic cream. im not sure if its doing anything or not though. and as for going to a doctor its hard enough even writing this here!!
