The gamemakers can ask any dumb Q they want ("sex in front of your friends or get your penis pierced" - related by a penis, but otherwise not). The original Q is similar to the stripper - magazine - porn (- escort) differences:
Strippers don't mind being seen (and seeing the customers), full face, by the strip bar public.
Strippers don't want their face out there in mags or videos.
Magazine and porn models are OK in the studio and they don't care how many goobers are strokin' to their images but they do not want to spend time too close to the hoi polloi. (Except for the new trend to promote their careers by AVN, shows, escorting, etc.)
The initial Q asks, Are you more concerned about displaying your private parts to people who know you (your friends) in private or displaying them to everyone in the whole world as long as you remain anonymous (assuming blurring works).
Your revised Q with face exposed asks, Are you more concerned about displaying your private parts to your friends in a private setting or to your friends - and a billion other people - in a video?
Or imagine the original Q such that it highlights YOUR personal worries. E.g., do I want just a few people to me go limp with this hot girl or do I want the whole world to see me go limp?
The original Q is fine: answer that how you like.
The modified Q is fine: answer that how you like
