We did have sex in the pool during the foam party and some of the couples outside the pool were annoyed (they said something like "right there in front of us" in an irritated voice) so both they and we moved somewhere else.
You might not be noticed much a ways out in the ocean, say facing each other, both inside a floating inner tube. We happen to have such a float ring... But remember its a public beach/ocean.
to red88vette: Platinum Wet, baby! Perfect for pool, hot tub, or dry land.
Everyone talks about how fun the "foam party" is, but I gotta say that the most fun pool event for us was the "Wet and sexy water aerobics." It's so fun if you love wet naked bouncing boobs, and who doesn't? Charlie (Chinese entertainment staff member) really designed this "class" well to make the most of the situation. Martial arts moves with our torsos above water, Busby Berkeley circles, make a chain holding hands and follow-the-leader weaving the chain through itself... not to be missed. Ah, gotta go back soon.
