First in my experience it take's a girl roughly 15 minute's to achieve an orgasm. Second make it happen by stimulating the clitoris of her vagina (It's a small nerve bundle that's not that hard to find) and third of all yes I have tried it and yes it doe's work and before you ask how I stimulated a girl's clitoris I used my tongue so enough said. If you want to find out more just google it. Hope this helped.

Oop's didn't catch the girl's only part,sorry.

it takes usually around 10-15 minutes
if you try ans achieve orgasm after this period of time they will come more frequently and thats when woman experience multiple orgasms
they feel amazing the 2nd.3rd.4th.5th etc times
i can go up to 10 times in a day if i let myself... of course tho i endure some pain afterwards but meh its worth the pleasure

I can have an orgasm within 5 minutes if done right.
Rub the clit or G-Spot?
I think every girl has.

I think every girl did that without knowing what they were called... :blush:

I read somewhere that female orgasms last 6 times as long as male orgasms.
