journeyman,
The conversation got slightly derailed, but there's been some research done on this. Basically, after ejaculating, you go through roughly an 8-day cycle where you will continually get more horny up until about Day 6, and then you will get
really horny through Day 6 and Day 7. However, regardless of whether or not you ejaculate by the end of Day 7, your testerone levels will drop dramatically and then level out until you finally decide to ejaculate later. But that testosterone spike will not come again until you ejaculate.
Here's the image displaying this:
This is exactly what I've noticed myself (and it seems you've somewhat noticed yourself). So what I would do when I was picking up women often was try to have sex within a 7 day period, with Day 6 and Day 7 falling on the weekend when I was most likely to go out to meet women. This would make me incredibly bold because I was incredibly horny

. But if I didn't bring home a woman by Sunday evening, I would usually masturbate on Sunday evening so that I could reset the cycle for the following weekend. If I didn't masturbate, I could feel my sex drive drop dramatically within the next few days, and I never noticed it recovering after that.
TL;DR: I masturbated once a week on Sunday evening if I didn't get sex with a woman to optimize my testosterone cycle.
