I've mentioned to a few people I'm close to that I've seen/see escorts. And the reactions can be fascinating. One was Aren't you worried about catching something? which when pointed out that he's be more likely contracting something considering the different women he shacks up with at Kellys night club every weekend it kind of made sense to him. Another (who knows I'm a loner hermit so wasn't surprised) after a while would get to talking about things I'd get up to. He'd say he'd love to try kink 'X' with his long term partner of 12+ years but it turns out he never even would dream of talking about it with her, never mind suggest trying anything other than plain old missionary under the sheet with the light off the way god and Ian Paisley intended.
Yeah, he has someone to come home to every day, but to never properly explore yourself or each other is mind boggling to me - all because you're scared of what someone might think.
