What does this mean?

So, my period should be coming in 5 days.

Usually, a few days before my period, I have noticed that my vagina gets so wet! Like, really wet and watery discharge. Also, I’m not horny but if I masturbate, it feels really good! My vagina makes me want to insert something inside or RIDE on a 🍆

Is it because of my hormone or what does it mean? Like, the medical term for it.

Thank you!

Gonna have sex with my bf tomorrow, hahahah so, hopefully my craving goes away ... and gotta have some before my period starts!
