Traveling to Barcelona with my sexy wife from June 15-20th. We are fit, late 30s, leaving the kids home for this trip.

1) Outside of swinger clubs, what local spots have a sexy fun environment? Is there a nighttime beach moon party, where ladies can dance in their bikini all night?

2) For beaches, we plan on doing Barceloneta, Bogatell and San Sebastian. I'm looking fwd to having tons of drinks at Chriniguitos all day, maybe we both will get nekkid. I know the last 2 have spots for that and heard Marabella too, but will my wife be outnumbered 10:1 by men?

3) are there any party boats for 10-20 adults, that are maybe catered to more mature crowd? What about pool parties at the W in June, will those be worth it or just stay at San Sebastian?
