It is very possible that her hymen is already broken, or she was even born without one. It can be broken during a number of physical activities (for example, horse back riding). Does she use tampons when she has her period, or has she ever fingered herself? If the answer is yes to either of those, chances are her hymen is already broken. If not and it breaks, that is okay. A broken hymen is NOT losing your virginity. Your hymen has nothing to do with virginity (unless of course it breaks during sex for the first time, but that is very rare now a days).

Touching her clit would be a great start. It is the most sensitive part of a female and would make her feel great. If you are clueless of what you are doing, all you have to do is ask. She will tell you what feels good and what doesn't, if you should go softer or harder, more left or more right. Communication is the KEY in sexual relationships, and you really should ask her the kind of things she likes. Nobody can tell you how to get her off except for her.

You can't make her ejaculate. Only 1 out of 10 girls are able to ejaculate. If she can she will, but don't be upset if she doesn't.

you have to be as gentle as you can when using fingers to stimulate the clitoris. it is extremely extremely sensitive and overstimulation can be painful! make sure your fingers are well lubricated with either lube or spit and take one finger (your index finger is probably the easiest) and gently and slowly circle the clit and stroke it. every girl is different in what she wants, so keep good communication and ask her what she likes, ask her if she profers it harder or faster or whatever.

me personally, i dont know if it is stage fright or what, but i find it hard/impossible to orgasm or even get much pleasure from fingering. oral sex is what does it for me. and penetrative sex. so basically, if one thing doesnt work for her, dont be disheartened! just relax and explore!
