I prefer trimmed on both. I would never expect a partner to fully shave or be disappointed if they didn't, however, much like the hair on your head, you gotta take a little care of it, make sure it's not going wild or anything And to me, that means trimming, so I'll ask if they'd mind doing that (assuming they weren't already). How MUCH trimming is up to the individual.
Hm, yeah I feel weird about this excluding gay/bi/queer/whatever folks
Buuut, I feel like I don't care as long as they don't shave. That just looks so unnatural and uncomfortable to me, and from personal experience I know what a pain it can be to shave so it's sort of a turn off when I imagine my partner going through that just for the aesthetic
If I'm giving a blowjob, they HAVE to be shaved. No trimmed or anything, shaved. I told my boyfriend that and he follows the rule. If he doesn't want a blowjob then he doesn't have to shave. It's my way of knowing what he wants.
I try to keep up on shaving but my skin hates it, so I have to modify the way I do things in order to make sure I can shave enough to keep him happy. He has told me he doesn't care but I know if he wants to go down on me, I need to be shaved.
