Hey Mark,
I'd like to WELCOME you here to the GYC.
You should definately visit the "Coming Out" forum, to hear some of our experiences, (it may help).
I honestly don't think you should lie about not being 'bi' or gay, if your friends won't accept you, then thier not real friends.
When you feel ready, you'll tell your parents.
I like your profile, it's cool.
Jay
Wow, "Hydroponics", we studied about it in school, it is cool.
