I can honestly say I have never sene the appeal of gaping. If you've just had anal sex of course, and you just happen to briefly see the gape, then you be moderatly interested. But other than that, I can't see the point.
Then again, I dont wenjoy vaginal gape either. You know, when a woman (usually in porn) will open "herself" up. That sort of thing would only interested me IF I was a gynocologist. And i'm ot. So it doesn't!
I must think....in normal circumstances I cannot imagine a more degrading humiliating experience for a lady to go through or a ladys husband to watch.
However we are talking about bringing life into the world and preserving live (both mother and child) It was a serious and heartstopping moment I will never forget, thankfully my wife has only vague memories. But it was very brutal and very neccessary.
