I've only had one that didn't smell great. Thankfully (?) my sense of smell sucks ass for some reason so I imagine that has something to do with it.It's been 50/50 for me on women's pussy stench. A couple girls I slept with smelled bad even after a thorough scrubbing in the shower. Couldn't keep it hard.
Last gf was so hygienic I could go down on her for days. Was heaven.
