needpehelp,
I know nothing about PE and curing it, but I think I probably have it and always have. I just don't worry about it. I probably should at my age, but I guess what I'm saying is that I'm no use to you as far as helping you last longer. I would listen to the rest of the guys on that. I don't want to give you bad advice, but I have a very different perspective on it. Someone said something about lasting the second time. That's what I always went for when I was young. But even if you can't do that, who cares.
I'm guessing you're relatively young. I think most young guys cum pretty quickly. I wouldn't sweat it. Joke about it. Tell her she's so beautiful that you'll probably cum in a nanosecond. But don't say that during dinner. Say it after things heat up. Also, say it with confidence. Or don't say it at all, but don't feel bad about it. She's a hot girl. You're a young guy. Trust me, I bet she's been with other guys who have cum quickly.
There's one thing that I disagree with that some of the others have said. I'm not sure I'm right on this, because it's probably specific to the individual, but just for a different perspective, you might want to consider this. I always noticed that I was smoother with women when I was horny. The hornier I was, the better I was at saying the right things to attract them. And it wasn't a small difference. It was significant. I could notice it. It was like my dick knew what to tell my mind to say. It sounds crazy, but I'm serious. It might have been an energy level thing. You're kind of peaceful after you cum, not aggressive.
I think the situation matters, too. It depends on how hard you're going to have to work to get her in bed. If you think it will happen no matter what you do, then I would disregard what I've said about not cumming beforehand. But, if you think you're going to have to be on your game as far as seducing her, I'd go with a loaded gun. You saw "There's Something About Mary", right? There's a reason the obsessed ex told Ben Stiller not to go out with Cameron Diaz with a loaded gun.
Take this for what it is - advice from a guy who never worried too much about PE. The PE gurus here might banish me from this forum forever for saying such blasphemous things, but I thought a different perspective might be useful.
Good luck.
