My strong preference is for whatever they feel comfortable with, regardless of whether that's 'natural', 'trimmed', 'part shaved', or 'bare'... but anyone who shaves needs to do it frequently, because stubble down there is still stubble.
I love to perform oral sex on women, so clean shaved makes that easier, but I'm happy to go for what ever the women is comfortable with. I don't have a problem with the women keeping her pubic hair.
Trimmed is fine by me..i mean in the sense that it isnt showing when wearing beachwear or similar. I tend to find that women get a huge thrill out of just laying back and letting me shave them. It turns them on enormously and the post depilation sex is fab.
Whatever my partner is comfortable with. Trimmed, landing strip, full bush, bare - I'm honestly not that fussed, if it's on a vagina belonging to a person I'm attracted to.
I will actually agree with guys and say that yes, without hair, oral sex on a woman is much easier but my boyfriend is happy with whatever it looks like. I 'get rid' of the hair because I prefer it that way, it's not about doing what he wants. It's my body.
