It depends on my situation.
While married and only sleeping with wife I would do it every time I was alone and had time. So sometimes 3-6 times a day while she's at work.
While on boat with no ladies around I do it every night (it helps me sleep) sometimes 2x a day.
While single and seeing ladies I didn't do it at all. Almost did after a couple of NCNS but got a ladies help before it came to that lol.
If you average it all out I guess the answer is a lot.
As for what I think about mostly ladies I have been with. Unless I am watching porn.
