The things that work for us are to have sex in public while on vacation. It is tastefully done and not flaunted at all. I'm talking about places like the hotel hot tub late at night when noone else is around. We once did it in a hot tub in full view of about 300 balconies, but it was hidden at ground level. Again we were careful about not making it too obviousl. We have also had sex standing in 4 feet of ocean with people within 20 feet. That is usually very easy to accomplish as long as the water isn't too cold
