Default Monogamy and menstrual cycles :D

In the book Sperm Wars, one of the main points is that "a woman is far more likely to conceive through a casual fling than through sex with her regular partner" and:

Secondly, and perhaps this is surprising, a woman is more likely to have routine sex in the two weeks after she has ovulated, when she cannot conceive, than in the two or so weeks before, when she might conceive. The difference can be detected statistically, but is too slight to be noticeable to either the man or the woman. This subtle change in behaviour is not due to a conscious decision by couples to avoid conception. Women using reliable contraceptives, including the pill, show the same slight changes in behaviour. So, too, do other primates. The subtle change in a female's willingness to have sex with her partner at different stages of her cycle is hormonal, not cerebral.
Some of the claims in this book make a lot of sense, while others are pretty dubious. I suspected this was one of the more dubious ones.

But now that I'm in an open relationship, and know everything that my girlfriend is doing with other guys, this seems very obviously true. Much more so than his "subtle change". When she's near period time, she's very "domestic" (her word) and monogamous and thinking exclusively about me. When she's near ovulation she's preoccupied with other boys, reestablishing contact with ones she hasn't talked to in a while, going on dates and sleepovers, etc. She says it's a very obvious change, too. Does anyone else experience this change in behavior?

Yes, I've noticed. I used to practice the rythm method where you take your temperature every morning and chart it to see when you ovulate. I became really aware of my cycle. I did this for three years and didn't get pregnant. It worked great for me.

I'm actually more indiscriminately horny during my period than at any other time, meaning I'm more likely to have casual sex and the like during that time, which seems to be the opposite as that thesis.
I can imagine that for a lot of people, they would be more wary of new partners during menstruation because some people can be grossed out by the idea of having sex during it. This being said as long as you're honest about, I find that many guys don't care and a bunch are turned on by it.
Not that I have casual sex anymore nowadays, but hormone-wise I can still tell I get horny thinking about lots of people as opposed to just my partner.

On the other hand I do have to agree with the "more domestic" think. I have that cleaning obsession during my period. I have theorized that maybe I feel unclean or I feel I'm making things unclean, so I clean everything much more as a result.

There are actually some very interesting studies about the different types of men women find attractive during their cycle. Documentary Storm/Documentary Heaven have links to some.

The week after my period is my crazy, want-all-the-sex time. My desire felt very "flat" when I was on the pill, but with an IUD I have ups and downs in my drive. My downs feel similar to what I was like on the pill. Being sex-crazed for that short time makes sex interesting!! Well, more interesting, I should say.

I haven't noticed any times that I feel more domestic. I mean, I get to be kind of a homebody when I'm on my period, but that's because there are two or three days where I'm quite crampy and don't want to do anything.

I am never feeling domestic, LOL. I hate cleaning no matter when it is.

On the flip side, I think I've always been pretty much the same level of horny no matter when it is. Maybe I just never noticed. I've been told that I am a "highly sexual" woman, but I've always wondered... compared to what?

I don't get my period anymore because I've begun entering menopause. The last period I had was October, so in a few months (after I've reached a year without menstruating) I will officially be a crone, or Wise Woman! Woo-hoo!
