Those bits you quoted are a perfect example of why I won’t interact with him anymore. Then again, I suppose it is kind of to be expected with someone who even chooses a name that is a bit hostile to everyone (even if it is written in the ridiculous net style of “1337”).
I don’t do any of those things either. The reason I know such things is from playing lots of multiplayer online games when I was younger (e.g. Counter-Strike before it was a commercial product and was still in beta).
I know a girl who gave her virginity to her twin sister. The sister gave her her virginity as well. They were in their early teens when they did that. I think they’re 30-something nowadays or so. They are still together quite happily too.
