I think there is a purpose for female orgasms. If there is no
pleasure in sex, why would a ger want to have sex ? except to have
babies? Is everyone's main purpose to have sex is to have babies??
Think most of the time is nope.
If a ger have no incentives to have sex, she will be less incline
to have sex. No sex, means no babies, = no people.
