(I'm asking this on this subreddit because I feel like you will give me honest answers. I sorry, I know the question got little to do with mens rights but I thought it might be fine anyway)

I met this guy (the host) at a party I went to with a friend. I gave him my number so I could fetch my stuff at his place because I didn't want to carry it around when we went to the bar/club. After the party he invited me to have an anime maraton at his place (we both like anime) I thought it was a good idea because I don't have friends that like anime in the area that I live in. I was a bit worried that It would be awkward because I'm not used to talking to people that I don't know and even less used to spending hours with them. But I wanted to go for it, I could make a new friend! I admit I was also a bit worried that he would hit on me. But it just didn't seem like he would for some reason. I was wrong. He sat close to me and sortof got closer and closer. He started to touch my elbow and so I made a 'no' sound ich. He stopped and I said thank you. But then after a while he put his arm behind me. I thought it was awkward and weird but didn't say anything because he didn't touch me. But then it sortof snuck up on me and it had just been to long to tell him to not have his arm around me.

I've have no experience with this and so I have absolutely no idea what to do now or what I should have done in the situation. I don't wanna hurt him by dragging it out but I'm so scared of conflict.

I have no interest in boyfriends/relationships. But to tell him that seems like a bad excuse. I also don't find him attractive at all which is just mean to say.

I know all of this might sound extreamly silly but I seriously have no idea what to do. Please help.
