Like many of you, I think that if a girl is attracted to you she'll fuck on the first date. If she doesn't, that either means she isn't that into you, or that she's using sex in a manipulative way, holding it off in order to play with you (to not look like a slut, to be seen as relationship material...).

If it's the first case, there won't be another date. If it's the second, I have the following strategy: when she texts me trying to set up the second date, I respond with "hey xxxx, you seem really cool and I had a nice time with you but it's clear we connected more as friends than anything romantic, let's leave it at this". What happens next (70% of the time) is that she answers right back in a very needy way telling me how wrong I am, that we really hit it off, and that "please let's meet again, I'll make it worth to you". And guess what, when we see each other again, she's the one trying to prove something to me and not the other way around. She is eager to make an impression on me, and by the end of the night she can't keep her hands off me.

I said 70% of the time, so what about the other 30%? Those girls tend to answer the text in disappointed way but don't press me further. Up until now my thinking was "well, I'm better off, maybe they were prudes and it would have been too much effort for nothing". That theory was proven wrong when I saw one of the 30% at a party a month after rejecting her. She was super-friendly and flirty, we started making out and she told me how bummed I was that I rejected her the previous time. We ended up together that night. But that made me wonder, maybe my strategy is wrong and "too harsh". I'm clearly losing some girls this way that would have been willing otherwise.

What's your take?
