In Heat?

Amanda
So online, I've read a lot of things about females supposedly going into heat. I know it's an actual thing in the animal kingdom where females are basically sex crazy. But at this point in time, I've been craving sex like crazy. Masturbation just isn't doing it at this point even though I've been doing it everyday for the past four days. I could just be extremely horny with hormones and stuff but I want to know if this is actually thing and if anyone else experiences it.
