Regarding public nudity and the common sense of choosing time and place. I've had some experience with "semi public" sex which meant that we were careful to be in a location like a car but also in a place with very low vehicle or foot traffic. Also, sex on a hotel balcony high enough that you "could" be seen from the street but pretty unlikely. The "risk" is a rush but don't be stupid enough to get caught. Jail and sex offender registry are not good ideas.
"The risk is a rush but don't be stupid enough to get caught."
Exactly! the risk is the rush. I do not want to go to jail or be labeled a sex offender.
