ANY MAN WHO CANNOT MAKE HIS WOMAN REACH ORGASM SHOULD BE JAILED…JUST KIDDING :)))
The clitoris is the most erogenous zone, but touching it along with rocking her vagina gently is powerful. But it is really advisable you touching, just touching her waist, her thighs BEFORE penetration.
Thank you for worrying about this…
Most men think that penetration is enough, but the truth is that during penetration, sometimes you don’t even get to stimulate the clitoris enough, which is for most women the most erogenous zone.
Ask your girlfriend, if you are intimate enough and she’s open minded.
