So, I had some dates recently and they were going great. Somehow I pussy out in the right moment though. How do I get over that?

One girl said "Let's go somewhere else" and my stupid ass was overwhelmed by that and then I fucked up.

Other time, we were sitting on a bench chatting, and were already a bit close. Instead of going in, I asked her to go for a walk. The chemistry was gone afterwards.

Any ideas on how I can stop that, apart from taking that situation as a learning?
