you should masturbate before you meet up with her.. so you can go longer

Kiss her and massage her and get her wet first. Then give her head and finger her (your fingers and tongue can't come). Finally, after a few orgasms she should be soaking wet (unlike with guys, the more orgasms you give a girl, the more sensitive she is). Now, slide your cock in her, she should come again. First, you need to know where her hotspots are: Clit: It's where her labia meet on top. It looks kind of like a miniature penis. Your tongue works best. Clitgasms are the most common, but not the most powerful. They typically last about 30 seconds. U-spot: The area above and on either side of her urethra (pee hole). Lick it and she'll have a pretty nice orgasm. G-spot: The G-spot is about two inches into the vagina on the anterior wall (ceiling). It feels like the roof of your mouth. Apply some pressure and make a scooping come-hither motion with your finger(s). She should start to feel warm and tingly and like she's being filled up with fluid. At some point she'll feel like she needs to pee. Tell her to let go, rather than hold it in. She'll start moaning and shaking and she'll probably shoot a clear substance out of her pee hole. This is not urine. Have fun watching her squirt as she has a mindblowing orgasm. Anal G-spot: It has the same result as the G-spot, but it's in the anus. It's about to inches in on the side that faces the vagina. AFE zone: This one's awesome. It's further back on the same wall as the G-spot. It feels rough like the tip of your nose. Make a scooping come hither motion (as you would with the G-spot). Even if she's not horny, it will send a signal to her brain telling her that she is. She'll be soaking wet and have a mindblowing orgasm within a minute or two. You can also just use it to get her ready and touch her somewhere else. Cul-de-sac: The Cul-de-sac is located in a cul-de-sac at the very end of the vagina on the posterior wall (floor). The Uterus has to lift up (which it only does when she's turned on) for you to reach it. Stimulating her Cul-de-sac results in the most physically pleasurable orgasm there is. Uterus: The Uterus is at the end of the vgina, wrapped around the cervix (which you MUST not hit, as it results in pain, that's why you must aim your missile up or down, not straight, to hit her deep spots). Stimulating in results in the most emotionally intense orgasm possible. It releases especially high levels of oxytocin, an addictive bonding chemical. It should also be noted that it involves no physical contractions. It is purely emotional. Nipples: Have her lie on her back or side so that blood flows into her nipples. Then squeeze them in-between your fingers. She should start to feel mildly weepy and emotional. This means it's time for you to use your tongue. Lick the tiny hole in the middle of her nipple, doing this for a while should give her a breast orgasm. Like uterine orgasms, breast orgasms release oxytocin, so you'll have her begging for more. NOTE: If you want even more intensity, combine more than one orgasm at once. As for helping you last longer, I recommend edging. When you masturbate, delay your ejaculation or even don't ejaculate all together. You can do this by slowing down or putting your hand down when you get close. After you've been doing this for a while, you should be trained to last longer. It works for me. It always takes me at least a half hour before I even feel like I'm getting close.
