Just my 2 cents worth on this whole thread....
I dont see why anyone would even care if this couple had 2 (or more) ads out there looking for different things.
If you reverse the situation and the couple had had a "straight" ad and bi female ad would anyone really care?
Could be lotsa reasons for the different ads...and as far as i can tell, no one posting here has contacted the couple in question to ask. Maybe he is truely bi and knows the general feeling of the swinger community about that so chose in the straight ad to tell them later if they should click. Could be hes simply bi curious and decided to run an ad and think about it. Could be that is wife is the one curious to see him with another guy and hes at least trying this for her, might be that theres an entirely different reason that i havent thought of..... My point is, without asking, nobody really knows.
My official opinion is that each couple or individual is into/curious about their own things. Their particular situation or how they handle or advertise it is really not anyones business unless a person/couple happens to be interested in one of those ads...then questions are ok so they can make their own decisions from there. If someone is not interested, then i dont feel its their place to judge one way or the other.
To the couple with the two different ads....all i can say is (quote from an old candy bar commercial) "sometimes you feel like a nut, sometimes you dont"
