Nowadays, with winter's chill setting in, it's like once a week. But in warmer weather I can get up to like once every couple of days. (I think my sex drive is pretty low to begin with.)
I answered 3-5 times per week. I suppose that's average for me. It's rarely less than 3 times per week. It's really difficult to say because there are days on the weekend where I'll masturbate 3 times in one day which will bring the weeks total to 6 or 8. I suppose we're talking about orgasms here and not just playing but not cuming.
My weight fluctuates a lot and when I'm thinner my sex drive is much higher. Like twice a day for a week plus before needing a break. But when I'm heavier it'll be maybe once or twice a week if that.
