TechRadar UK - Why are games so terrified of sex?
For the most part this is as far is anyone dares go. Actual nudity, graphic sex scenes, or even characters commenting on the fact that the team's new Paladin looks like she funds her adventures down the local docks are never actually mentioned, leading to the most incredible coyness.
