no, you cant, most of the stuff that big bang theory says about world of warcaft is completely made up, for instance the fight on the gate where sheldon steals the sword and sells it on ebay, impossible to do with any major sword in the game, because its un-tradeable, the episode where sheldon had his ostrich stolen (not even a real mount), you cant steal mounts that have been used and since he was 85 if his mount was used he couldnt even take it off the account since in cataclysm was the 85 patch and the mounts were all on the account mount page. The closest thing you can do to sex is take off your clothes but even then you are not naked, they have default clothes on. also you can mod to take the default clothes off but no one else can see it, its client side so its useless, you can have as much sex on wow as you can typing someone on yahoo messenger except you don't have webcam access. dont listen to anything that show says when it talks about games, they just aren't accurate.
I have played the game since vanilla, which means since the game came out.
