Yay for healthy masturbation! I don't do it every day, though I used to. I started when I was 12, which I guess is young for a girl but just right for a guy lol. (i'm a girl).
I love to masturbate! It relieves stress, quells (momentarily) my huge sex drive, and is just very calming. Plus, if you masturbate when you have menstrual cramps, it can help releive them by controling the contractions of the uterus which is what causes the pain in the first place :p
i have a steady bf now, for over a year, and we have a lot of sex, so I don't feel the need to masturbate as often. I still do, sometimes though :) it's me time.
