Teenage girls

It's funny but I love women I love pussy but I don't like to look at teenage girls, and I cringe when other guys my age go on about teenage girls. I have 17 y o daughter and the thought of guys my age looking at my girl makes me cringe, do you think this is a natural reaction and do you think I would feel different if I didn't have a 17 y o daughter. I blocked one guy on here cos he was going on about teenage girls
