The first time I had oral was terrible, but that's because the guy had no idea what he was doing. And it was a little awkward, simply because I didn't know him that well. But in general? No, oral sex is not awkward. And when it's done right, I make plenty of noises. There are different positions in which you can receive oral, so you don't just have to "lay there." And even if you are just lying there, you aren't usually just lying there; there is lots of tensing of muscles and limbs for me (my legs always shake during good oral).
