My step dad makes me uncomfortable

I honestly don't know if I'm overreacting wich is why Im just gonna post on here to save myself the embarrassment. I just wanna add some context, they have been together for Abt 3 years and I am 13, anyway. He has always made me uncomfortable even before he started saying things about me, since he would always put me on the spot by asking if she loved him, then would say start talking about their sx life. Not in great detail but he would just give me information on how she supposedly wouldn't fuck him anymore.

Then he would just make weird sexual jokes in general, like about other people and tell me his sx story's with other people in way more detail. After that he would start mooning me ( this was when he was drunk since the last year he's been off work and has been drinking a lot so all of what happens here on out has been when he's drunk) this might be where I start overeating so I hope someone will tell me if I am, I would usually laugh it off and run away since it didn't seem to serious even though I was severely uncomfortable. This next one has been a lot more recent he has always asked for hugs and would always smell me deeply ( like in the movies rlly weird) the few times I did let him hug me. But this time I didn't want to so I went to run away and he grabbed me, wrapped his arms around me and started kissing in a sloppy manor all over my cheek and neck this lasted like probably 3-6 seconds but it felt like forever, this was when I started feeling gross.

About 2 months ago I decided I was gonna "dress up" bc I felt like it so I wore a skirt ( Wich wasn't short not like it matters) with leggings and a t-shirt as I walked out he looked me up and down for like 2-3 seconds and said that I looked nice now this might be another over reaction since I've never had very affectionate dads in the past. Lately he's been calling me "baby" only whenever he asks for something, then I give it to him and he'll say "thank you baby", he always says he liked how my hair looked when it was up, so I cut it off so short that I couldn't put it up anymore. He always says I smell good so I change my perfume then he says I should change back to the other one.

Lately, in the middle of a conversation he'll just seem to get flustered Wich is all I can describe it as, it usually happens when I'm next to him leaning against something looking up at him as I'm talking and then he'll turn to look at me, then he gets all weird and says " go, just go." I'm obviously confused as I'm talking to him so I'll usually laugh and ask why then he'll look at me up and down rlly fast and tell me to leave, this has happened I think 3 times in the last 3 months. This one happened a couple hours ago, I was on his bed while we were yet again talking, I was on my left side stretched out with my right leg hanging over the bed ( my left was straight) I was doing in this position bc I jumped on the bed to pet my cat and so was he, I guess he didn't realize what position I was in until he looked down ( he was standing over the bed) and then abruptly stopped so I looked up at him as I was talking and he then looked at my waist or maybe legs, I don't wanna immediately say butt bc I don't want to jump to conclusions but he was looking somewhere waist down. "Don't do that" he said I was like " what?" Then I realize where he's looking, I'm not completely sure if I said anything as I got up since it's kinda a blur. Also as I was helping him make his bed he kept making jokes that if I didn't hurry up then he'd have to get naked, I get the joke bc he sleeps naked but it's still weird to say to someone who turns 13 in a month. If anyone reads this please give me some advice or tell me if I'm overreacting, I have had a last with perverts in my family and have been sa'd before so I might just be projecting onto the situation so please give me feedback, and I'm sorry if there's typos I'm kind of frantically typing this.
