Is the way I think about girls abnormal for an 18 year old guy?

Can I marry you? Seriously to a female what you are saying sounds so good. Your the knight in shining armour. Lol. I am 18 and there is nothing worse than guys looking at me and they have that look on their face that says ' I am picturing you naked'. WE HATE IT. I have a few good guy friends who are the same as you and they range from 18 to 25 so I wouldn't worry about it. My ex was like you until he became conceited. Don't change, please.
