Actually, I doubt they're 'attracted' to the smell at all. I mean, obviously if a girl smells really bad they won't want to go down on her, but at the same time, I doubt most guys sit around smiling and think of how girls poon's smell.

I know how hard it is to get over an irrational concern about a body part. Trust me though, I imagine your fella won't care as long as it doesn't smell or taste bad. (and most of the taste comes from our sense of smell anyway-so as long as you're clean, you won't taste bad)
