Having access to the Internet was one of the most important factors in my coming to terms with my homosexuality. Without the Internet, I'd never have gotten laid.
I can't even imagine how much better my life would have been in high school if we'd had the Internet. I didn't really have access to anything beyond email until late freshman year of college. In the early 1990s there was a near-total media blackout on anything dealing with being gay other than AIDS stories and the occasional show like Tales of the City on PBS which, of course, you had to watch while it was on in real time or hope no one noticed you set the VCR to record it.
