I set a boundary?

So there was this guy that liked me and he would make comments saying how if I saw him in a different state me and my mom could crash at his place he was telling me like sex jokes or talking about certain things. Got his friend involved where his friend befriended me and I know that they were trying to get information from me but the guy was also saying how much you like my pants and how much he likes my clothes a lot he even asked me if I like when guys make the first move. You would also make sexual jokes a lot. I don't know if he really liked me. I just had a feeling anyway he was seeing somebody and they made it official and then he got really weird around me when I knew and then before he left he wanted to hang out with me so he brought his friend. He just was talking sexually, saying how he likes this other girl who was in a relationship with somebody else I'm kind of making fun of her a little bit and I had realized like they had put their status as complicated which I don't know what that means. But I am visiting that state and I was like told his friend like hey do you think he'd be okay with me hanging out with him even though like he has a girlfriend I don't want to overstep boundaries basically saying like I just kind of want to be his friend I don't want to be involved in whatever cuz I don't think that's a good idea. Basically I told his friends like I know the reason you talk to me is because of him and everything and I just think being his friend is a little bit better and I don't think making sex jokes around me so no one gets the wrong idea. Was I being over dramatic or or thinking about this on the wrong way I never said I hated the guy I just think it'd be better if he didn't make those kind of comments or stuff like that when we hung out so we just know we're friends even though I do like him I don't want to be that person
