I rather take offense to Responsibility #7: "Don't fool around on your significant other."

Could you please amend that with "unless they're into that sort of thing"?

Thanks. Otherwise I won't be allowed to strip for my girlfriend in front of all her other friends.

That's not fooling around on your significant other, it's fooling around with your significant other.

Perhaps I should change it to "Don't cheat on your significant other," as that would make it more clear that swinging, threesomes, open marriages, and (since you mentioned it) consensual exhibitionism aren't being ruled out so long as everyone is in agreement. What do you think?
