How to boost orgasm potential

I have a hard time having an orgasm. Is there any way to boost my orgasm potential? Vitamins, foods, anything?!

Make sure it's quiet. Set the mood. Tell your partner to talk dirty to you. He should be really into you, and focused only on you. He should have your undiveded attention. And you should tell him to move different ways. Always try something new. Find out what works for you.
