As I see it, there are two separate categories of sex. There's the sort when you're with someone you care about, and you care about their pleasure too. And then there's the sort when you just want to fuck someone as if there's a camera in the room and you're in a porno film.
If you can fuse the two, then you've got it made.
Some of the most exceptional experiences I've had were with WGs, but that's because they fulfilled some specific demands I may have had at the time. But it was 'porno' sex. Nothing wrong with that, but it's not the same as a deeper experience, even though there may be less 'skill' though, that you'd get with a real lover.
