OK, I know this may be graphic to some, but I need advice from a male point of view. The other night, I was waxing the small of my fiance's back when he told me that he wanted me to do his buttocks. I did them up both until where they meet (the crack

) when I noticed that I accidentally dripped wax in between

! I quickly when in and had to spread them to wipe the warm wax and I noticed that he had what looked like a bunch of bumps raised off by themselves. I know he has stomach problems and bleeds when he goes #2, so I'm thinking that maybe they're hemmoroids. If they're not hemmoroids, I would like to know if they are due to an STD - I know he has been with MANY women besides me. My question is how does one ask about these things without embarrassing or upsetting the other person?
