Wetting Myself First

I don't do it anymore but when I was in my teens and twenties I would often wet my underwear, making it sometimes warm and damp, sometimes hotly pee-soaked, before I would get myself off. Sometimes I would pretend that I was a boy or a girl being tickled while wrestling and flirting with another girl, tickled so hard that I wet my pants. At other times I would pretend that I was a girl being taught to masturbate by another girl; she told me that to come really hard, I had to let all the pee out, first. It was incredibly erotic for me (and worth the extra laundry, too), especially since it made my crotch not only wet, but warm. (I know now that some women do this too.)
