Of course it varies with context... e.g. if you're Canadian, you may consider Angolan exotic, and viceversa....
I'm not sure what constitutes 'exotic', but my first sex outside the the was with a Kenyan hooker. We'd spent 3 weeks at sesa and I was well ready! Hong Kong was superb, I was there a while back in the '60s and had an oriental girlfriend called Sophie. She was one of the best fucks I've ever had! In 1970, I was on the bullet train in Japan. It was packed solid. It was so tight I was getting a hard on from folk pressing against me... A japanese student (male) had felt me, persisted in rubbing my crotch and at my stop, followed me off the train. This was around Osaka. He signalled for me to follow and we went down a small alleyway. In no time at all he had my trousers open and my cock out..... Wanking & sucking it. I LOVED it! No words were spoken, he just finished me off and went on his way!
One of my exes best friends, spanish filipino mix, sweet jesus was she fun, fucked and sucked like no other and her pussy smelled and tasted amazing
A ONS with a Japanese woman named Leah. Born and raised in the US yet bilingual. She was an interpreter for Japanese importers who visited. Met her in a hotel bar and 2 hours later met her clean shaven pussy. She had silky jet black hair, dark brown areolas, with long nipples just aching to be sucked. And those eyes. OMG her eyes were mesmerizing. Woke up the next morning by her side and just watched her sleep. Hated that I had to get to a morning meeting before catching an afternoon flight home. Softly woke her with kisses before I went to my own hotel room. We exchanged numbers but never followed through. Maybe for the best as it remains one of the best memories I have.
