More and more women are choosing celibacy exactly for this reason. They’ve had too many bad experiences in the past and it’s just not worth the effort and emotional toil to keep trying. Julia Fox recently shared that she’s 2 years celibate.
As someone that enjoys sex, my natural inclination is to say “but it can be really amazing, you just need to find the right partners” - but you’re totally valid for wanting to throw in the towel. I mean, if everyone in the world loved traveling (just a random experience example) but I tried it and the locals at every place I traveled to treated me like shit, would I keep trying over and over again? Nope.
It sounds like you wanted to experience good sex though, so I’m sorry that it hasn’t worked out for you the way it should have. Hugs!
