Nick Justice,
Firstly, let me assure you that there is nothing wrong with you.
And you should assure your partner of the same. There is so much pressure on the partners but women have to 'learn' to orgasm and most of that is on themselves. Please do not take this to mean that you're at 'fault'..if there is such a thing here. Learning to orgasm takes time and best of all, practice! I've always found that the easiest orgasm to have is a clitoral stimulated orgasm (rather than a g spot orgasm). Try this out. Oral. toys. Most importantly...and I cannot stress this enough. HAVE FUN with this. If you're stressed about it, it will not happen. So relax and once your partner is reassured "baby, it's me not you"

, she will have just as much fun playing.
