so i am 18, not ugly or anything and i like to create my own manga and music so i have some hobbies, but sometimes i get the feeling i am missing out on possible relationships with females. i am mainly talking about a serious relationship. in my class i dont have a crush either. when i go home with the train, sometimes i see a girl i think looks pretty or kind looking and want to tell her how i feel, asking her number to close it off. i just don't know if i should do it. would girls be comfortable with random guys walking up to them saying that to them? i want to do it but nobody has convinced me to do it yet. if people say i should do it then i will give it a try. what do u think? and what should i say?
