I want to change my name/surname.?

Hey, I've been thinking about it for a long time and I think its time to change to do it. I know that some people think its wrong and that you have to respect the name that your parents gave to you, but I really hate it. I am man but my name is typical girls name in English speaking countries, so when I send email to someone or text they think I'm a girl like wtf, hate it. My second name isnt that bad for ME, but no one, NO ONE can pronounce it.. even though I think its easy... When I was called up in the grad m to get my certificate , it took principal 3 minutes to pronounce my surname, well it was embarring. I'm still not sure but I think it would make my life easier in the English speaking countries. Whats your opinion?
