For me it depends on my stress level. When i have high RW stress i need to release, usually once a day. Then there's times where an insatiable women knocks my dick in the dirt and i'm good for.............a couple days ;-)
I am hornier more often than I ever have been... also find myself thinking about things more risque than I've ever thought of before... must be just reaching my sexual prime. Sometimes it can be very frustrating if I don't reach an orgasm with my partner because masturbation doesn't seem to satisfy me at all.
