It varies. I do webcamming, and sometimes I consider it masturbation, other times I think of it as acting. It depends on the chemistry of the other person involved.
When I'm just getting myself off, I find that I have a normal if not healthy sex drive, but I masturbate infrequently. I like longer sessions and I don't always have time for a ridiculously long session. A quickie is a like a snack. Had the urge then took care of it.
If I'm trying to flirt with someone, I just don't masturbate at all. If I do, it kills my mojo... Sometimes being "sexually frustrated" can help make you do a lot of things you didn't think were possible, like clean, or seduce a man halfway across the country. It can be magical. Lol
