Am I overthinking or am I wrong or do I have a right to feel this way

Hi idk where to post this, hopefully this is fine.

I don’t know if I’m just overthinking this situation, or if I have a right to feel some type of way.

So growing up I always had thick thighs/ an ass. My aunts on my dads side would always make some type of comment every time they seen me , no matter who was there, sometimes I’ll just laugh with them. Can’t avoid it.

This April, we threw a party for my little sister she turned 20. As I was fixing the table so we can take pictures one of my aunts made a comment on how the pants I had on made my ass look bigger and I need to move it out the way. Bc people was tryna pass by & I just stayed quiet & continued what I was doing & people laughed. Then my dad said “ I can see her ass so big bc she got it from me” something like that, it went quiet & my other aunt said you have no ass & my uncle changed the convo to the food. thankfully like when my dad said that comment in my head I was like what type of dad is looking at his daughters ass. My back was facing him as I was fixing the cake table they was in the kitchen .

Well these last two weeks at work( I work some night shifts with my dad) , I’ve noticed my dad would like “accidentally” hit my butt or bump into it with his hand not his body. He doesn’t say sorry. Like there’s space behind me for u to walk and you still “bump” into me. Like no. At first I would ignore it thinking it was an accident but now it’s happening every time we work together. Im start to want to be away from him, like if he’ll come stand close to me which I normally wouldn’t have a problem ,now I have to move away, I don’t feel comfortable , he would usually like hit me or poke me to scare me and now I don’t even want him to touch me at all & I don’t wanna tell my sister or my mom bc what if I’m just overthinking the situation & don’t wanna make things worst and it maybe actually just an accident and he doesn’t see it like that.

I don’t live with him btw , I live with my mom. I only see him at work & that’s only bc we work together 3 nights outta the week if not I wouldn’t see him. I’m 21.
