Foreplay. If you take longer than he does, have him give you a head start.

Try to make yourself orgasm first to experience what it is you are searching for. Masturbate yourself and just find methods thats you like the best.

Foreplay is good for getting you really horny. Also, if you masturbate and can orgasm successfully through that, you can try using similar techniques during sex.
Another thing, clitoral stimulation can help eg. rubbing your clit during sex or having your boyfriend do it (if he's in the right position). Don't be afraid to do this, your boyfriend won't mind and it can just help build up the pleasure and lead to an orgasm.
It is hard to orgasm for a lot of women, through penetration alone hence why a lot of women like clitoral stimulation during sex.

I agree...masturbation is the best way to find out what works for you. I know what works for me, but that may not float your boat...so. jill away. maybe your boyfriend would want to help out. :wink:

Let him go down on you to start, that's usually the easiest way for a guy to make a girl orgasm (if he knows what he's doing :D). Once you start to experience orgasms that way, they'll come naturally during sex. Good luck!

i agree, you may need to masturbate to find out what you like and don't like then you need to communicate with him on what turns you on

There are some girls that can't orgasm, just make sure you are relaxed and focus on the feelings...also listen to the others

Well, it could be one of many things. Some girls your age don't have orgasms. Don't think that just cuz you having sex, you need to get an orgasm. It don't work like that. What many women do to reach their climax is they masturbate. And I'm serious on that, cuz us guys sometimes don't know shit what girls want. But you girls do, so you need to explore your vagina and see what feels good. And once you find what is good to you, then you can teach your boyfriend what he can do to make you climax. Try letting him lick your pussy as if he is a shark wanting to eat your meat. You need that aggression. Also, let him put his fingers in your pussy and let him lick your clit simultaneously. See what happens, and if all that fails, call me. Hee Hee.
