Obviously I'm a girl in real life but recently I changed my mains name from Naomi (my real life name) to something else. All the time i get guys whispering me trying to make conversation and wouldn't leave me alone. But gender shouldn't matter, When you befriend them and get close just ask.
I see no reason why I'd need to know that. So it doesn't matter. So I don't try to find out. And I feel I'm happier that way. People behave differently as soon as they find out who/what you are. And that causes things to be kind of uncomfortable.
