Buy Curious

It is not the first time, that I have been left confused rather than curious about a real estate ad.

5 questions popped into my head as I stared at this ad:

1. Is it a condo for the bi-curious?
2. Is it a condo for nudists?
3. Are those the real-estate agents or models?
4. Is the guy on the left looking down at the woman's coochie or at the guys schlong ?
5. Why isn't there a fifth (person)?
