Ladies I need your help!

So I've been seeing this guy, we've hung out and done just like friend things, but the main reason I see him is to fool around. We met through my cousins boyfriend, so obvi he's friends with people I know. Anyway, when we fool around (I'm 18) we usually make out, and end up going down in each other(usually pretty late at night) Well one of the times, we were making out pretty hard core, but I really wasn't getting into it. He, on the other hand was. I got to the point to where I knew I wasn't going to get off, so I ended up giving him a bj. At the end, i was tired and didn't even want him to try to get me off, so we just cuddled and went to bed. At this point I would have happily gone home and not thoughbanything if it, but he asked if I wanted to stay. Anyway Here's the kicker, my cousin told me, that the guy I was seeing, told her boyfriend  that I just come over, suck him off, and go to bed. Like he totally cheapened me. I feel so disrespected, like I know guys talk but he made me sound like a total hoe! When we've been mutually getting each other off for weeks. Please no judgement ladies, I was having no string attatched fun! I though we were mutually just having a good time with no complications! I don't usually do this kind of thing, like ever so I didn't really know what to expect. Any way I want him to know, I know and that we're done. I'm having a hard time wording what I want I say so I need your help!
