Well I definately think one can tell when there's chemistry.Of course, chemistry may not be there immediately when you meet someone. It could develop or appear later. Something could just click. Even if he may not touch, kiss or "whatever" exactly the way you like. I find it better to say "I like it when you kiss me like this" and show him or " I like it when you touch me like this" and show him or " I like this" and show him.Being subtle about it, but defintely letting him know what pleases you. Not being mean or embaressing about it, but still letting him know. So he learns what you like, but doesn't feel embaressed about not pleasing you.Making it a kind of a sexy game, not being mean about it. I find nothing wrong with letting others know what you like as long as it's done politely. Everyone enjoys being kissed, touched or whatever differently and the other person doesn't really know what you may like.
