I resonated to EVERYTHING in your story and, of course, got very hard and had to masturbate.
It's also like meditation for me-several years ago read the Margo Woods book on Tantric Masturbation and began extending the amount of time I spend masturbating. I quickly get myself up to the point of cumming and just stay there for at least an hour or two right at the delicious edge of cumming. After about 30 minutes I seem to enter another dimension-I'm still aware of the sounds around me, but time and space seem to become irrelevant. The orgasm that cums after all that edging is WAY beyond anything I've ever had in traditional partner sex. The net result is that, like you, I'm not looking for a woman for 'sex.' I'm completely self sufficient sexually and identify my sexual preference as Solosexual.
I have also videotaped myself masturbating and love to masturbate while watching myself masturbate either on tape or in the mirror.
I masturbate every day, usually 2-3 times, and it would be the ultimate completion of my life to someday live with a woman who masturbates a lot every day, fully expects to see me doing the same, and doesn't need ANY other sexual activity.
