Somewhere along the line, i started feeling bad about the fact that i invite a girl over, have sex with her and after never call her again. I don't know where this came from. I used to do it before, multiple times. But recently i paid attention that i didn't get laid for about 3 months now, because i am looking for a girl that i will be willing to call her back after our first sex. (LTR Material).

How do i go back to that state of mind?
