I traveled around most of Europe with my parents when I was 15. By far, the most surprising part about Europe was how relaxed you guys were with sexuality. I'm from the south and being open about your sexually is generally frowned upon. But in Europe? Boobs. Boobs everywhere.
When we first touched down in Belgium there was a museum which had an exhibit called 'The Art of Orgasm'. I found an ad booklet in Switzerland for watches that was just 20 pages of attractive women making out. One night in a hotel I discovered that most of the channels on the TV were soft core porn.
I shared a bedroom with my parents for most of the trip.
It was a challenging time for me.
