I do like both, but when it comes to choosing my partner's oral sex or a toy -- sorry toy! A toy cannot even compare a tiny bit to my partner's oral sex. I love using toys as foreplay and we use them together (him using them on me and me using them on me), but there's nothing like his oral.
I don't like being on the receiving end of either, actually. I like giving oral, but not getting it, and I don't really get very much out of having toys used on me. Orgasms just don't appeal to me all that much.
