You're not the only one. I'm evil enough to let my MC die as a single man in his first life. 
My Poor Characters
I mean, the MC in my current novel died a virgin when he was beheaded in a fiery car explosion.
But that wasnt horrifying. It was hilarious.

Haha, now I don't know whether to take comfort in that or feel bad about your MC.
You a bad man, Clowniac! 
Hm. I like to start at my characters childhoods so there is always the chance they die before they achieve anything in life. Hehe

I did joke once about killing off my MC and turning him into a Panda. I still think I should do that as an April Fools sidestory chapter.
kazesenken I remember a translator did something similar for a BL manga. They translated the entire conversations using love songs and BL clichés for an April's fools. I was reading and wondering what the hell was going on until they had a panel that basically said we got you.
No kidding 
in my story I wrote that my FL was sexually molested when she was a child...by her adoptive father. I felt like crying and so disgusted writing the scene 
God knows how badly I wanted to end it.
