Is sex this satisfying or it's just them?

Just them unfortunately

It’s most certainly is this satisfying when your madly in love and very sexually compatible sigh ╥﹏╥

I mean yeah, but not this long girlie

It can be. Especially when feelings and kinks align, in the right moment, with the right person. But it takes a willingness to be vulnerable with other people, with yourself, and to not shame yourself for unabashedly enjoying sex (which is imbedded into most cultures), and for them to be able to do the same.

Tldr: Yes, it is. But it’s hard to find and takes work.
