(22M) I generally have no issue approaching a girl, whether that's someone I met through a friend, someone I see at a bar, or someone I meet online (Tinder, etc), and once I score a date with a girl, 9/10 it will end in sex, because I've practiced and practiced how to date perfectly (I have a whole routine that I follow every time). My problem is that although I can really like a girl while we're on the date and do my best to charm her, the second we're done having sex I lose all attraction and become completely emotionally detached. I then usually don't text them again (dick move, I know, but I really can't help it when I feel so completely not attracted to them anymore).

I would like to pursue a more meaningful relationship (I've never had a girlfriend before, only one-night stands who I never see again afterwards), but I'm scared that I'll find a girl I really like and then lose all interest once we sleep together. Has anyone else had this issue? Is there anything that can be done to become more emotionally invested?
