It not uncommon for some hetrosexual men to have thoughts and interests about other men. Been curious to know what your friend at the gym looks like while in the shower? - it's just curiosity. the strap on - I know many married couples where the man wants to experience penetration and the feeling of prostate massage (very nice) And having your wife rim you is a whole new level - try it some time Curiosity is healthy - Maybe Hetro-curious may suit you?
