I lost my virginity just before christmas and since then I've have sex 3 other times. He seems to come but I can't seem to orgasm. Is there something wrong with me or with technique? Advice is welcomed

some women never actually orgasm while having sex... you need to practice and get to know your body...

TOTALLY NORMAL!

It takes time to learn your body, his body, and enjoy proper foreplay and position you like best. He may be too quick, and not stimulate your clitoris etc... he may be learning himself. More importantly, hope birth control is involved and good grades.

That's not unusual. Why do so many people expect so much? First of all, quick anatomy lesson: the vaginal walls are not all that sensitive the farther in you go. It's entirely possible the time you feel him most(discomfort, pleasure, just an awareness of penetration) is just when when he enters you.

The first few inches of the vagina are the more sensitive part, particularly the side facing your front. I'm sure you've heard of the G-spot? The standard method to find it consists of 3 steps:
1) place finger/s, palm down inside you
2) start making a sort of a beckoning motion
3) keep making this motion until you find an area that feels "different". It might almost feel like having to pee for half a sec, then it feels good. You may need to apply a bit of pressure

Try to see if he can angle his (I'm sure very nice) cock thataway, and it might be better.

Clito.ral stimulation is also very important. One suggestion would to do it doggy style and stimulate yourself manually or get him to (all he needs to do is reach around and rub a certain rather sensitive part of the external female genitalia)

Sex, like anything, requires practice. Get to know your body, try new things. Heck, a good chunk of women can't come through intercourse alone anyhow, so don't be so worried if it isn't easy. Just relax and have fun :)

Personally, I've never had a vaginal orgasm so don't be worried. Clitoral stimulation is the easiest way. Try being on top and grinding against his pelvis... trust me lol

There is nothing wrong with you. Foreplay is so important. Just need to relax and not have so many expectations. You let yourself go completely and with lots of practice, maybe just maybe you will get the surprise your looking for...

Yes, it is normal, but however you have to find it on your own, try masturbating by yourself and most likely you'll have one and be able to find your g-spot on your own.
