tinder hook up

So last Friday night I was bored so I went on tinder, something I’d never thought I’d do. This super cute guy asked me over to his friend’s place for drinks so I thought why not and went. He was gorgeous and a total gentleman at first. He asked me to stay the night so since I had been drinking I did. We watched a movie and had sex. Not normally something I’d do but whatever. Next day I went to leave and he asked me if I could ride with him to his house to pick up some things. We went to the store then his house and he asked if I could take a nap with him since we were up all night. Afterwards we went back to his friend’s house and it was his friend’s kid’s birthday party so I said ok well I’ll see you later have fun and he said “wait you’re not coming to the party?” So I went and every time I’ve tried to excuse myself he asks if I want to stay. I spent all weekend with him until I took him to the airport for his training seminar. He texts me throughout the day and calls me most nights for at least 30 minutes. The dilemma I’m having is that almost 90% of our texts are sexual in nature and I’ve encouraged it by telling him I’m his personal whore. It’s fun to mess around since I don’t know what I want but at this point I’d assume he wouldn’t call to ask about my day if he didn’t care at all. I just want to know what this means from a guy’s perspective. Sorry this is long..any response is greatly appreciated. I’m not clingy or looking for a relationship just want some insight so I know if I should allow myself to consider getting attached.
