First of all, im a college student, never had a girlfriend, but have had sex multiple times.

Why is it that when i meet a girl and sleep with her, as soon as i get any sort of sexual contact (even just making out), theres no way i will like her. For example over the summer I had a fling with this chick who liked me, and i just wanted to get my dick wet so i hung out with her a lot but never developed any feelings for her so i always felt like "just get your dick sucked." I would and instantly afterwards I felt like this "fuck now i have to hangout with this chick for another couple hours"

If i get to know a girl and start to like her first without any sexual contact, were now friends and theres no hope. (its not like ive been friend zoned, just that i started the relationship with no intent to fuck, aka we werent man to woman as RSDtyler would say)

TL;DR: If i like a girl, i cant get them. If i dont like them, they want me and ill use them for sex but then regret ever meeting them as theyre just a waste of time

edit: not sure if this was the right subreddit but was as close as i could find
