I have a buddy that has a above average penis and his wife has below average vagina. They barely have intercourse. They mostly do non intercourse stuff.
It actually pretty bad now that they want kids. They are considering IVF since it hurts too much for his wife.
Not only that, they post the wiring diagrams online and even have a video tear downs.
Here is an example.
