Is NOBODY wrong in the post ? POST : TLDR: Mature 16 year old daughter wants to date, I won’t allow it because as bad as it sounds, she’s a girl. 

I have a 16 year old daughter. She’s beautiful, does amazing in school, and is constantly  surprising me by how mature she is. 
I often ask her for her opinion in family matters she probably shouldn’t know about, but she’s always levelheaded and  gives pretty good advice. She’s only ever slipped up twice. I’m a devoted Catholic, and when she was 12, she refused to go to church and told us she didn’t believe in God. This hurt me and my wife deeply and I’ll admit, I yelled at her until she couldn’t talk anymore since she was crying. Not my proudest moment, but it happened. To this day she doesn’t believe in God, but the condition of her staying in our home is that she at least attend church with us. 
The second time she slipped up was when she was caught shoplifting. The cops let her go and there’s nothing on her record, and she said it was like an itch and she felt so terrible about it. I don’t let her walk around alone in stores anymore. In her defense, she’d been dealing with severe depression and mental health issues at that time. 

Now, the other day she comes to the living and sits down. She says she has something to talk to me about, and that she knew I wasn’t going to get mad. It looked like she was about to cry, but she said that she had met this boy who she’d liked for a year. Apparently, on New Year’s eve, he’d told her that he’d liked her for a long time and he really wanted to be her boyfriend. 
She said she wanted to let me know and that she really liked this boy. I generally am very strict, so my kids don’t go out much and aren’t allowed to date until I say so. Years ago, I said that the age when they could date was 16. She recalled this and said that she was 16 and she just wanted to get my permission first. 

I appreciate this, but I meant that my boys could date when they were 16. I love my daughter but she’s my only girl. I know she’s mature but women are easily manipulated and I just want her to be safe. I told her that I’m glad she asked, but it was a no until she graduated. I think she expected me to say yes, as her face dropped. She nodded but she’s the type to fight until the end to prove she’s right. 
She brings up how her brother dated at 16, and how I’d let her younger brother date at 14. 
She keeps this up until I am forced to say that it’s because she’s a girl. This clearly upsets her and she stands up to leave. But first she just says that she loves me but she’s disappointed. 

She’s still upset but I don’t think it’s that much of a problem. I’m not trying to be sexist, I’m just protective over my daughter. I know she’s smart and mature, but men can be dangerous, and I don’t want to put her through anything.
