Horny

I don’t really know what it feels like to get horny. I mean, i think I do, but I don’t 100% know. Me and my friend have been sending nudes anonymously and I’ve seen parts of his dick. I was in class and I was remembering one of his pictures. I could feel my heartbeat in my vagina. I’m assuming that’s what getting horny feels like. I just want to be completely sure.
