there are some pretty decent nude beaches in the usa. rules are
rather strict though, they won't allow a towel wrapped around your
waist. it's a place where people toss aside their worries and enjoy
the peaceful environment of the beach. if you are wondering, very
few people actually chose to have sex there. most of them are
either sunbathing or walking around.
as for nude parties, i've never to one before but i heard they are
all the rage now. young people often go to these parties, usually
bithday parties where the birthday guy or girl is in his or her
birthday suit and the others follow. i doubt it happens in
singapore.
