Girls can have orgasm more than guys. Girls cums easily as they
have the g-spot and those with protruding 'love button' will
orgasmic easier as the guy thrusts forward. When a girl has an
orgasm the passageway does contract as the love juice flows out.
Some girls do not have as much love juice but their love hole is
very moist. If she is your gf for a long period of time, and its
not the 1st time you make love to her, I guess you can tell fake or
real when she moans at the moment she has orgasm. The maximum
number of times per nite a 2hrs session a girl can cum 22 times,
wet the bed badly though.
