I'll still go down on a woman if her pussy is hairy, but I prefer she shaves. I almost always go down on a female first until she cums because (1) I don't have to worry about her complaining about not getting hers when I cum; and (2) she seems a lot more sensitive and easy to satisfy after she cums from giving her oral. But I have a lot of spontaneous sex, so she doesn't always have time to wash up first, and there's nothing I hate more than going down on a female and tasting urine in her pubic hair. If I taste it too much I won't go down on her long, and generally, all around, the sex session isn't that enjoyable.
