Hey everyone

I've posted on here a few times, and your advice has really helped (i.e. how to tell my g/f about my foot fetish, etc.).
I wanted to know if you could help me out, so I could help my g/f out. We've been going out for a year and a half. We're both virgins (waiting for marriage), have great communication, an amazing "sex" life, and we are deeply in love.
Here's the thing.

She doesnt believe that she's ever been able to have an orgasm. She said that it's in no way, b/c of me; she says that I always make her feel really really good, and I'm not doing anything wrong at all. The problem is that she says that the intense pleasurable feeling will build up inside, whether it's from me giving her oral or rubbing her clit or fingering her, and then as soon as it gets really good, all of a sudden it starts to tickle, and she has to have me stop b/c it becomes too ticklish. Taking the advice of the people from this board who have given other people advice, I told her that she has to feel comfortable...maybe tension or aniety or pressure for it to happen is causing it to lose it right at that moment. So we again tried it with her in that relaxed mindframe...same result.We talked about female ejaculation, and I asked if it felt like that peeing sensation, and she said that it kind of did..and how it also felt like a tickling sensation that just becomes too much to handle, in more of a negative way. I don't think it's an instance of her pushing me away due to the tickling feeling, as many girls do after they've had an orgasm or at least "finished". Yeah maybe she just doesn't recognize that she's had one but, she says that she's pretty positive that she hasn't and that the tickling feeling that makes her make me stop, occurs right before she can cum. She also says that she feels like she would be able to squirt.

So, I wanetd to know your thoughts, b/c I really want to jump this hurdle for her b/c I want to make her feel as good as she makes me feel...that's my number 1 priority, to get her to orgasm, and stop the tickling sensation that is acting as the gate stopping her from reaching that final phase.

Also, if you guys and girls have techniques: oral, fingering, g spot, clitoral, etc....the best of the best secrets, post them here too.

P.S. We've somewhat explored the g-spot, but haven't quite found it yet..and I'd like to be able to find other ways to make her cum, besides the g-spot as well.

Thanks so much everyone!! Looking forward to your advice!
