So my wife and I don't have sex on a regular basis like we used to. Its much more opportunistic due to busy lives, health and stress issues. From time to time I get pretty horny if its been too long. I've noticed however that When she gets her perod that feeling subsides. Anyone else experience a drop in sex drive when a significant other has her period? Is this just conditioning? (ie I know its just not going to happen until her period is over so i subconsciously adjust) Is it pheremones? Is it something else? I wonder if I can use this to control inconvenient urges at other times. Any thoughts?
