My parents think I'm gay

It all started last week when I had some friends over. They decided it would be funny to leave gay porn saved on to my computer. My parents were the first to find it. We had a long, awkward conversation at the dinner table and they didn't believe me when I told them it was my friends who did it. They started to check my computer every once in a while, and they soon started checking my emails. Someone had sent me a fake letter saying something about thanks for subscribing to our fag porn site. My parents had a talk with me about this also. Now they think I am gay and they won't allow me to bring any of my male friends to my house unsupervised. This sucks. What should I do to prove that I'm not gay?

BTW my parents are hardcore catholics. They hate gays.

i dunno, get a girlfriend, get normal porn on your computer for them to find, uh...  make up some story about how reading the bible turned you UNGAY or some shit - i'm sure they'll love that.  what else...  make sure you have your spmn filtering gay shit like that for when your parents search your e-mail...

above all, vigrously scrub your computer of it's gay contents.  If your friends won't stop "sending" you gay porn, do the same to them and then confess to THEIR parents that "some of the things they were showing me on your computer was making me uncomfortable" and now their parents will think they're gay.
