"First you need to buy genitals," is the absolute last thing I want to hear about my future sexual relations, but in Second Life it appears to be a prerequisite for cybersex. I've never thought much about Second Life, other than enjoy stories about how nuts people get over it, like it's the real world. Seems that the human mind is really good at reprogramming itself for new contexts, so to the users, it pretty much is a real world to them. "It would just resemble two clunky-looking characters rubbing their bodies against each other..." oh, wait - it really IS like real-world sex!
