I'm a 20 year old female and I don't masturbate. I've tried to finger myself/play with my clit and I don't really get any real stimulation, I've never made myself cum. I have a relatively low sex drive compared to my friends. If it were up to me I'd probably just have sex about 1-2 times a month. However, I actually have sex about 1-3 times a week to satisfy the needs of my partner. I find it odd that I don't masturbate because I was under the impression that everyone does.
