Not really a kink as such. I had a very prudish upbringing- no sex before marriage and all that. Sex has pretty much become marriage in my head. It almost feels like a spiritual thing in a way- a joining of souls. Not that I am all that religious or spiritual. Still, it's not something I'd do casually because it would utterly mess me up emotionally. I'm actually glad I realised that though- it could have ended up in a lot of heart break otherwise.
Kind of irrelevant anyway though because I'm not at all attractive! That's more the barrier if I'm honest. Even if someone did by some miracle find me attractive, I doubt I'd have the confidence for it.
Plus, there's the concern of STD's and for women specifically- getting pregnant. And also, the high possibility of suicide in the future. I don't actually want to be creating more tethers to this life. Especially not in the shape of people. Doesn't seem fair on them.
