hey how about not writing in all caps?
I'm bi. I never bothered to tell my parents. I feel like that would be saying "Mom, Dad, I just wanted to let you know...I have sexual intercourse with men and women. I ride c*ck, AND I like p*ssy."
It seems a little unnecessary. I mean, whatever you do is your business, why would they want to know or need to know unless you are in a relationship with someone that is serious? I don't even introduce them to people I date unless I am being extremely serious with them....as a result, out of X number of people I have hung out with/dated/slept with, they have only met....(drumroll)....3 people I was with.
As for the homophobic comments, just say, whatever, that's your opinion, keep it to yourself, a$$wipe...? Or..."That was really rude, but whatever"...something like that...?
