The only sexual stimulation I've ever had in my life has been masturbation. I like women. They arouse me and I often fantasize about sex but after 30 years of masturbation I'm no longer really interested in sex with a woman. None of them could possibly live up to my fantasies and at this point I figure it's safer and healthier for me. No STDs, no unwanted pregnancies, no relationship to worry about.
I understand that 30 years of jerking off has ruined me for the real thing but it isn't all that bad. I've always been a loner and kind of solitary anyway.
