How do I talk to my parents about being emo and having a boyfriend?

OK I have 2 questions. Number one I am one of those emo people who likes that kinda stuff. My parents don't support or like that. How do I tell them this is who I am? Number two. I have a boyfriend and they don't allow it. They don't think I am responsible enough and to tell the truth I haven't given them any reason to think I am responsible. Me and My boyfriend's parent's are this way and he really fears his parents as do I. How do I tell them about all this?

well just so you know emo has nothing to do with cutting (self harm has its own catagory)
so tell your mum that. if you dont self harm, it will help you to tell her.
emo is a genre of music and now a style of dressing. is this what you like about it?
tell your mum that you are emo, and the things you like (that you think accossiate with being emo)
and remember, emo is just another stereotype. like punk, goth, prep, nerd, jock, ganster, ect, ect!
you need to be honest, so tell them you have a boyfreind. and be prepared to listen to her if she gives you a 'sex talk'! mothers will do that, and its important that you listen.
tell her your a responsible kid, your not doing anything bad, and you feel ready to go out with a guy...

yeah I like the clothing and music though I used to cut and recently quit with the help of my pshycologist
