AITA?

My fiancé’s love language is physical touch and I don’t like being touched a lot. Every single time he hugs me…(leaving the house, coming home, going to bed, just because) he finds the need to go up my shirt, into my pants or try to unhook my bra. I just want a hug, and I’ve explained I don’t like that especially since it happens EVERY single time we hug. He gets frustrated with me when I stop him, but I’ve told him why.. then it creates awkward tension… am I being the a$$hole here?! For context- we’ve been together 3 years, lived together for 1 1/2 years, and we are both around 40 years old.
