Re: This lay would be a bucket lister! Please help!
Eh, you could always go caveman and give it an all-or-nothing shot if you really wanna give it a whirl before she leaves. I have had about a 25% percent success rate with my method.
Also you created buyer's remorse because she didn't really know you, you had her going, but she has had some time to "come to her senses." You avoid buyer's remorse by making sure there is rapport, connection and a perceived depth to what the two of you share before going for intimacy, that way she doesn't feel like she got "stiffed"...heh. I made a punny.
I actually slept with a girl one time just because she wanted to and hated myself for it. She started really liking me and I had to reject her and felt like crap for doing it in the first place. I had buyer's remorse. The best way to avoid it is to simply not sleep with a girl just because you need to catch your nut, but rather choose women you actually do share a connection with so that neither of you regret it, that you are happy you were able to share the experience together.
Also after sleeping with a woman make sure to give some small gesture to show you still care, such as a text when you wake up (if you didn't leave after sex) telling her you had a great time and are glad you were able to share the experience with her. You want something that isn't needy, that doesn't pressure her into something but does show her you didn't just use her as a cum dumpster.
