Why is that some of my friends find masturbating disgusting...?
Because American culture and society teaches us that mas* urbation is gross and shameful especially for women.
A lot more women do it than you think... we're just taught from early on to act disdainful towards it.
SO of course they would say it's disgusting... but I bet I know what they do at bedtime!
Maybe they dont find it disgusting.Maybe they just pretend that they find it disgusting.Or maybe they find it disgusting because it dirty their hands.^^
Simple. With those friends you should not talk about mas**bation. No other step or change needed.
