Unusual sex drive all of a sudden.

For the past week, sex with my boyfriend has been feeling different. I'm more into it and find myself throwing my butt onto him, wanting him to pound my walls out. Normally it's a bit uncomfortable. I don't really yearn for sex because my boyfriend doesn't really put much effort into turning me on. A kiss here a lick there, and a quick rub anywhere and he's ready to go. Now I actually think about and once I get it, I don't want to stop.

Is it because I'm in my fertile window? Or at least that's what Glow says.
