I started when I was about 18, would do it once a day, maybe every other day. It was interesting to me at first, but two years later I stopped enjoying it. It was still some time before I was able to tell myself that it was OK not to enjoy masturbating, so I stopped. My sex life is actually better because of it; there's no stressing about climaxing and I get to focus on the sensations that I really like.

For the record, I am asexual, agendered, and have had a greatly diminished libido since starting birth control for my endometriosis. I'm much happier with my low sex drive, actually.
