hello seddit. My problem is i lose all interest if i know i can get a one night stand with a girl. How do i fix it???

Yesterday i had oppurtunity to have a one night stand with 3 different girls ( at different times in the night). I dont know whats wrong with me. I know that i had 99% chance of getting some, but i instantly lost interest in the girl after i knew it. Yes i had escalated, kissed the girl, touch her, without being needy. Playing totally cool. But i fucked up, i just left. Example of how i fucked up: Me: you live far way? Girl: yes, very like 40 minutes. me: i live like 10 mins from here alone. girl: wow thats cool, maybe i shouldnt go home today. Me: up to you, i go home now good night me: "leaves"

im so fucked, pls help.
