Married straight male, 38. I'm pretty good looking and have a big dick (8")... but I also blow my load really easily. When I was single this meant I got lots of dates, but disappointed every one of them. Now that I'm married, my wife sometimes finds my lack of stamina annoying, but she's pretty non-sexual so it's not a big problem.
Like a lot of married dudes, I sometimes fuck other women. Usually I stick to pros (either massage parlors or escorts) since they don't care if I cum fast and aren't likely to tell my wife, but I've been known to fuck online friends too.
