The feeling of sex is good, and the feeling of being in a committed relationship is good. The good feeling of sex is often implied by a committed relationship, but is still attainable outside of it. Important to remember that these are distinct feelings.
how do people have casual sex i’ve never understood it i feel like to me sex is supposed to be like this really special vulnerable thing to do with someone involving love so much and i really don’t know at all how i would react to doing it casually
No they’re not supposed to be distinct. Having sex with someone you’re not in a committed relationship with is just pure degeneracy.
