It's a very personal choice. There is a very wide variety of preferences on the matter. I don't shave or trim any of it. I have had a few partners for sex and oral sex, none have complained.
Personally, I think bald pubic areas look disgusting. They just remind me of children, which is pretty much the last thing I want to be thinking about during sex.
I feel a lot sexier having all of my pubic hair because pubic hair is my body's way of saying, "Hey, look at me. I am a full grown, fertile woman who is worth your erotic attention, yes I am."
Shaving may increase the chances of getting razor burn, bumps, ingrown hairs, and even infections down there! Ew. So if you do try shaving, and it disagrees with you, you can try leaving it intact, trimming, or waxing instead.
