i think the way you’re describing the process as “screwing around, forming and cutting off attachments” really shows that you think of it in a very black and white sort of way. one can have casual / fwb sex with their friends, and still have a friend relationship with that person. one can even have one-off sex with an acquaintance or stranger, and even if you never meet again, it doesn’t really make it a “cut off” relationship; if you met again, it would be pleasant, circumstances just may not arrange it

just because it’s a more emotionally involved process for you or some people you’ve encountered, doesn’t make it a universal truth
