Should I do it or nah?

I do some event planning on the side nothing major just some extra income when it's available!!! Well the other day a friend of mine asked me to plan her swingers event!!!! My jaw dropped because I had no clue she was into that lifestyle!!!! So I have never been to a party or a club and don't really know what have or set up for her event...I been researching and asking a lot of questions but not sure if I wanna take on the task!!! What would you do????
