Never in a million years did I think I could be.... but I think we have just recently been proven wrong. About a month ago the wife asked me to stop when I'd gone real deep during missionary, then afterwards she complained about being sore and asked me to inspect. She had a tiny slit in the bottom side of her hole. After some time off sex a couple of weeks later the same thing happened again when I got her legs into a certain angle and drove downwards into her and getting right down to the base where it's possibly a bit too girthy as it goes from 6 to nearer 7.
This is not the first time she's had little injuries like this having previously got them on the upper side by her clit and we've never really known why or how she'd got them. Well we now think it could possibly be my dick causing this and I perhaps need to not thrust at certain angles any more.
So you could say I've literally split her vagina. lol.
(She was not impressed with that joke).
