Relationship advice/ help!!

So this guy and I went on two really good dates and now we hangout at least once a week. It’s been at least a month or so since we hit it off and went on the first date, but now I just come over on late nights to do things with him/ kinda like a booty call. The conversations have been smaller and the amount of times we hangout have been shorter. Should I be concerned I’m getting into a hoe type relationship rather than dating? Or do I need to just talk to him about it? He originally said he never wanted to date from the beginning that he’s “talking around” but last week he introduced me to his best friends as “his girl”. His mixed signals have been keeping me up! Please help!
