This, make sure your girl has spent time masturbating. (I know plenty of girls in the late teens/early 20s that barely know how to make themselves come.)
And, like said, it's pretty much based on the individual. Some girls can come from penetration, some (many) can't.
>implying women now what they want especially one who has never even orgasmed
Start by putting in 1 fingee and then make a come here motion about 2/3 inches deep, look for the spot that feels like rice crispies. Then start rubbing her clit and put in 2 fingers, slowly go faster. Do this for like 2 mins until she cums, after then stick your little pee pee in and just focus on rhythm. Sex is unironically not hard I dont know what virgins problem are
