I will say I like both - but I prefer "front" or vaginal, as we ladies like to call it . To me, anal always has to begin with a vaginal warm up, and it's sort of ... how can I explain it? It's nice when I'm really into the heat of the moment, very turned on, ready to go. But I wouldn't want to start with it, cold, right out of the gate, if that makes sense. But they're both nice. To answer your question.
Of course the vagina is also accesible from the rear, so I am not sure if that is the front or the rear. A hand job, blow job, titty fucking, and a foot job I suppose would all be the front. So I guess I am not sure if "front" includes vagina or not, but I suppose it does, so the question the way I see it really is "Does a female prefer anal sex over giving a guy a blow job, hand job, or foot job, letting him fuck her vagina, or titty fucking."
I've tried anal a few times, didn't really enjoy it at all, i prefer vaginal. BUT when my boyfriend is going down on me a finger up the ass does feel nice
