Second Life sex is a thriving industry. This is perhaps the only game that lists a steampunk-themed homoerotic sex club and an island devoted to having sex with anthropomorphic cows on its official website as "places of interest." This is possible thanks to the users who spend hours programming the animation for avatars having every conceivable type of sex, since that s**t certainly doesn't come with the game. One such user is former plumber Kevin Alderman, who saw a need for a service and filled it with pixelated penises.
Plus one very sad digital wig.
Alderman, using the pseudonym Stroker Serpentine (which sounds like Harry Potter's former teacher who can't go near a school anymore), created hundreds of animations of Second Life avatars performing lewd acts. Thousands of users each paid Alderman the equivalent of $46 in real-world money so they could pretend to have sex within the game, because sometimes chatting one-handed just doesn't cut it anymore.
So successful were these animations that when a teenager in Texas copied them and tried to sell them on his own, Alderman found the kid, brought him to court, and eventually obtained a settlement against him. But Alderman's biggest accomplishment was much more ambitious: He was also the creator of the sex capital of the virtual world, Second Life's Amsterdam. Using high-resolution photos of the real place, Alderman painstakingly recreated the city of Amsterdam, right down to the canals, the train stations, and the hookers.
