Well, you can’t really just have casual sex and expect to find any sort of deep/significant emotional connection or bond from it.

I’m sorry for what you’re going through, but if you want that sort of connection again (if you think you can even find it), then you can’t partake in this toxic hookup culture. Intimacy is built on familiarity and trust. It’s something that’s born out of things like investing time, sharing secrets, overcoming hardships, laughter, and mutual joy. All of these things form a love attachment - and what is sex without love? What is it really worth? Nothing at all.

I would really recommend you not to rebound any longer and instead focus on healing from this breakup. When you feel ready, enter the dating scene again and form friendships first. First trust, then love, then intimacy. It makes for a much stronger foundation.
