I've been on both sides of this issue in the last several years, and in my accidental research, I have found that when I was skinny I had less stamina BCD. I'm not sure why that is, but it's true.
Now that I have packed on the pounds, I could easily (and happily) go for multiple hours. This could be due to my age and the sexual peak I am supposed to be experiencing at this point in life, so my research may be worthless. All I know is, I used to get tired after an hour, and right now, an hour is like foreplay.
As far as the women I am attracted to, I tend to like women who are curvy and 'thick', my ethnic preference being beautiful, thickly built, AA ladies with dangerous curves
