My girlfriend and I have been together for 3 months. I am her first partner. She has never had an orgasm before and I have tried masterbation and oral sex to help her achieve one, but it has still failed. During sex she says that she doesn't feel anything from it and it usually hurts her a little when we start, but she says the pain goes away after a minute or two. My question is what techniques should I try so she will have an orgasm and what methods should we try to make sex more enjoyable for her?
