Am I wrong to tell him not to touch my stomach?

Me and my dad aren’t as close anymore since a couple months ago when I found out he wasn’t in my life for a while and cheated on my mom and did drugs and everything like chose to go to a friends and do drugs instead of be at the hospital while my mom was giving birth well not the point but I’m pregnant I’m 30 weeks and he keeps touching my stomach I hate being touched sensory issues I’m not sure I hate being hugged touched or anything I nicely asked if he could stop touching my stomach as it made me kinda uncomfortable and he’s like why ru like this all the other family thinks it’s rude all this, and goes on about how it’s not normal and how he should be able to touch it and that he’s my father all this. I just honestly don’t wanna be touched that’s all it made me uncomfortable I expressed that and he’s being all idk about it. Is it wrong to tell him to not touch my stomach. Also if other people tried I would say the same thing.
