When I was 16, I had surgery because the lack of a vagina meant that I was dying from all the blood decaying in my uterus.
The first time I had sex at 18, it was short and insanely awkward because it felt like he was sticking a large knife into my abdomen. I didn't say a word and after a few minutes, I stopped him and went directly to take a shower. I cried for like half an hour and bled a ton. I had sex rarely for years because the level of pain was more than the level of fun and I felt horrible after every time.
That was like 10 years ago and it's still painful sometimes but not nearly as bad and it's much more fun.
I don't like spanking for unrelated reasons. I like being bitten and choked, both sometimes really hard but that's a different kind of pain than the stabbing-my-crotch kind.
