Perfect. You can be the first guy to give her an orgasm. The other day I gave a girl an orgasm, I was the first guy to ever do this to her. She's 24 and I'm guessing been with quite a few guys. She was so astonished by my "ability" she couldn't believe it. You know how good it felt to know that you're the first guy ever to give her an orgasm? For her entire life I will now be the first guy to have given her one, and she will most likely always remember me for that. If she's with another guy who can't do it, she will think back to me.
Fuck it's great. Read the Sex God Method, I'm reading it now. It helped me out a little.
As for not being sexual then and there, don't worry. Stop overthinking why she never had an orgasm. Just know that the fact she brought it up means she's thought about sleeping with you

Be dominant, don't take her shit, be nice and funny, and just have a good time when you take her out. Know what you want and go for it and be unapologetic about it. Then make your moves.
