Is it normal to have these horny feelings?

Let me just make this quick and easy. I've been horny and turned on for the past 72 hours. And i got more hornier when my guy friend slammed me onto the bed and dry humped me. Then grabbed my pussy hard to the clit. I told him to stop so he did. But i totally wanted him to go on. Then when we were about to leave our room he hugs me and we fall back onto the couch then he starts rubbing on me. And slides his hands down in my leggings. I absolutely loved it, and typing it out makes me love it more. Im starting to like him, but then i lose that feeling often though? Like its an accent that turns off and on constantly. He used to date my best friend , and i feel kinda hoe-ish. But i just loved it.... So i guess this shouldn't say "is it normal to have these horny feelings?" but to say "what should i do?"
