About a week ago when I was washing I noticed a white bump next to my anus hole. I have applied some sudocrem to it and been really gentle around it but it doesn't seem to have gone away and i really am too embarrased to go to the doctors unless 100% necessary. It is not at all painful and i doubt i would've noticed it unless i had felt it. I would describe the texture as being similar to skin, maybe very slightly rougher. It is about 2mm in size. I am 19 years old and sexually active but only ever with one person, who is the same.
