I'm a lucky one. My wife has no problem with orgasm anymore and she's a squirter.
She used to have problems but that was because she was letting her mind get the best of her. She was scared to orgasm or she'd be stressed etc. Most of the time it's guys who have that problem. Anyway, the best advice I can give you and I'm going to assume you are female, is to not think about things so much. Just enjoy the feeling. Try different positions. Many women have a hard time reaching orgasm in the standard missionary position. Try variations of you being on top. You can control and make it hit the spot when you want.
