Is he a pervert?

My brother swears he not a perv but he does DISGUSTING things like if I take too long in the shower he threatens to pull me off of the shower regardless of if I’m naked or not and one time he even opened the door and he said he “didn’t know I was naked” ...he doesn’t know but I caught him taking pictures of my mom naked under the crack in our bathroom door. He seriously scares me and I get scared to be in the house alone with him because I’m scared he will sexually assault me bc he makes sexual remarks at me and says it’s a “joke” or he will lay on top of me and try to hump me and I tell him to get off of me but I can’t push him off bc he’s bigger than me. He will also try to make me touch his private parts by grabbing my hand and trying to put it there. I’m sorry that has nothing to do with the original point of this post but I felt like it would help paint a picture of what’s been happening

Edit: also before anyone says anything my mom was there when he tried to pull me out the shower naked and she heard him tell me he didn’t care if I was naked but she clearly didn’t care she was more mad that I cussed at him
