I enjoy it to the extent that I've refused to date guys who don't enjoy receiving (yes, there have actually been a couple). It's true that it's a power trip. It's true that hearing the moans and seeing the faces that you're causing make it that much more exciting. For me though, it's the physical act of doing it as well. Feeling the weight of a cock on my tongue (especially feeling it grow in my mouth) is incredibly erotic to me. For me, that "full" feeling (vaginally) that women talk about, applies orally too. The feel of the skin... Pushing myself to take it as deeply as I can... Contracting my throat muscles around it... All very sexy things. I don't think anything tops a man who will take control and use my mouth as he pleases though (providing he's not trying to suffocate me haha). Not only is that a huge rush, but it's a great way to learn what you're doing with a dick. Anyway, now I'm babbling because I've managed to make myself horny. So, there's my two cents on the matter.
