I have never had a preference and neither have the women I have been with.

I think innie and outie can vary with how aroused the girl is.
I will have to cheat at cards.
It depends on the couple and what is expected after it happens.
I have never applied any scientific criteria to it but I have shot several feet on certain occasions. Pulling out after a long session seems to be the best method if I was going for the Olympic record. I have aimed for a girl's belly and hit her face totally by accident of course. I have never gotten out the tape measure but just estimating I think 3-4 feet is my best.
