But normally a guy asks the girl he likes on a date right? I think i would not do that bc i am too afraid he would say no and jokes about you. And you can also be romantic without giving gifts like for example wanting to be together, holding hands or sitting together maybe under stars or in a park. In school i think guys often dont care about it but maybe a lot more when they are older. That is a LOTTT nicer i think. Because being romantic is NOTTT like being weak but i think sometimes guys think that at school (at least in my class).
In traditional roles, yes. It's just my opinion, but I see romantism just like peacocks who display their feathers and dance in front of females; even though it's probably a little bit more complex! However, just like you are afraid that someone says no and makes joke because you asked out, it seems that people are more and more afraid of talking to the other sex since a few years.
I don't know if men become more romantic by growing older. I suppose not everyone grow a romantic fiber, and that it comes with how your relationship with girls go. I couldn't say much though π
