Is it wrong of me to be this protective?

I'm am a single mother of a 16 year old girl. She has a few guy friends but no bf's she ures me she don't want to have until she's out of high school at least. These guys she's hanging out with are real bad boy types I know she is turned on by. a few of them I don't like cause I knew guys like them. I tried having a talk with one of them and he actually tried to gently move me out of his way with a smirk on his face. My daughter was in the shower so I twisted his arm behind his back (I'm a bouncer at a gentleman's club) and forced him into the wall, he struggled but I just hurt his arm more and told him he better respect my daughters wishes and he better not push her into something he'll regret. I know my daughter is one of those hot girls and I just don't want her to be unprotected, I taught her some moves but she's not big and strong like me. Was that wrong of me to push her bf around? She came home and smirked at me after they went out. I asked her what, she said nothing and that she loved me. My question is, is it ok I get these boys aside and intimidate them like I do? Am I hurting their ego forever?
