I have encountered a few guys who were, as the saying goes "fit but you know it" - and he's thought that just being fit, you should be grovelling all over him and giving him freebies.
There are some clients who I genuinely fancy and I would submit their photo to some kind of "I banged this hottie" website. (Obviously I wouldn't really do that, I mean hypothetically.)
But actually the clients who I tend to fancy and get a bit weak kneed over aren't "conventionally" good looking, there's just something about them that has made me go sploosh. The last major one of those was when I was in Chelsea and he came in and commented that I had a book out on the table by Chimamanda Adichie, and we then started talking about Amy Tan. If you're not a book nerd like me then this will mean nothing! We started kissing and cuddling on the bed and it was honestly more like a first date with amazing chemistry than a booking.
TL;DR - talking to me about female authors will get me wetter than just showing up with six-pack abs
