Well, at least the ones i know of in RL. They can probably hold it till the end of the world.
Bullshit. Every sexually active, healthy, mature girl masturbates. A lot of girls are embarrassed because of stupid societal reasons, people thinking they are dirty sluts and loose and the such. I am truly offended that you wrote that. (BTW this is all coming from and anti-feminist)
When Spaz is at work and I didn't have cats watching my every move I averaged about two to three times a day. It's not because we don't have sex, it just puts you in a better mood and lowers your stress levels. Now I just do it when I take a shower without Spaz.
It is very hard for girls who don't masturbate to enjoy sex at all, you have to be comfortable with yourself first and know what you like. So in other words if your girl says she doesn't masturbate, never really masturbated, and she loves what you are doing, she is lying about one of them, or you are god's gift to women.
Also men who claim they don't masturbate are full of shit, have wet dreams, are a male hooker, or last about five minutes in bead (15 minutes of slow boring sex with 30-40 second breaks).
Of course i was exaggerating to prove how weird they are. Also they think masturbation is disgusting. Maybe i'm just too young.
