Ah the Golden Girls. As a foreigner I always found it quite interesting how such a relatively prude country had a major tv show that revolved around old people having sex (with Rue McClanahan apparently sucking off half of South Florida).
We are aware sex exists but we prefer to segregate our lives into subtle and sometimes not so subtle innuendo and porn. I personally have no problems with sex and nudity but I don't need to be sitting on the couch with my mother watching a TV program at 8pm and have boobs in my face. The older I get the more I think of it in the same way as gratuitous gun fire and explosions. It's just indicative of a lack of creativity on the part of content creators.
