I just answered this Featured Question; you can answer it too!
Maybe a little too comfortable, but I don't see anything wrong with it. It's a way I can define myself as a sexual being in this world. I personally think it goes further than just the physical act. Desires, thought processes and really any mental attitude. Having said that, of course there are other ways to express those. It's definitely not a taboo in my world.
(I needed a break from my over-packed, full of work life. So I took the time to answer this featured question.)
