Masturbating cycles

I'm a guy, but I find myself going in cycles of masturbating daily if not more for a couple weeks whether I have sex or not... some days I'll cum 3 or 4 times between my hand and my wife. Then just not doing anything at all for a couple weeks before starting up again, it's nothing conscious. Just how the urges strike me... anyone else like that?

I can certainly relate. There are times when I am not really sexually active at all, and other times have major urges and will cum 2-3 times a day. Some of this has to do with hormones; Gonadotropin Releasing hormone (one of your main "sex/reproductive hormones") is released in intervals, not constantly, so there may be times where you aren't super sensitive to it and other times when it can be much stronger/overriding.
