It can't hurt knowing your partners cycles. But they aren't going to stay on their set schedules, so don't be surprised if they jump track.

For example, I've read that women prefer more generically masculine men when they are ovulating, so during this time, the partner could change their bahaviour to be a little more wild and reckless.
The motives for WHY you would want to keep track of your partners cycles are poor though.
That there isn't my particular motivation for knowing a partner's menstrual cycle. I was just using it as an example. Hell, I don't even have a girlfriend; and probably won't in the foreseeable future. I just don't think I'm very well suited for relationships.
You should be you, and never not put up a front of fakeness. Your partner may or may not have these masculine desires- but that's up to you to determine from time spent with her- not a website.
Actually, I didn't read about that on a website. It was in an issue of science illustrated. There had been a study that showed that women's preferences in men changed during their menstrual cycle. More specifically, they would prefer burly masculine men when they were fertile, and when they weren't as fertile they were more attracted to sensitive caring men that would make good fathers.
As a result, they were more likely to cheat on their partners when they were ovulating.
There is much room for variation within a personality, and what I'm saying is that bringing out your masculine side when your girlfriend is ovulating, and your more sensitive caring side when she's "infertile" might very well do a lot to keep your chemistry good.
Of course, a lot of this is the doing of hormones and pheromones, so I'm not sure you would even have to make an effort to do these changes. For all I know, you might do it subconsciously.
