And, when I do not, it's usually more of an objection to the 'why' than the 'what'
I find that communication before the first date gives me a better sense of the person I'm about to meet. Sometimes that's a great thing. If he's really nice, it makes me feel excited and reassured. I can look forward to spending time with someone new and exciting
Other times, I get a sense that he's going to be a PIA to some greater or lesser degree...and, that sense intensified with each email. Then, I have the option to back out of what could have been an unpleasant experience...or at least, prepare myself mentally.
I generally find communication between dates to be extremely enjoyable. Most of my clients are interesting people. They like to keep in touch... they always have something interesting to say...they never overwhelm me with novels, and rarely with factoids about their favorite sports team (a topic about which I am highly unlikely to have any genuine concern).
The very few who overwhelm or irritate me are boundary crossers. They are actively trying to change the nature of our relationship, from provider/client to something else entirely (sugar baby/daddy, or even fuck buddy/buddette)...and, sometimes, they have some REALLY intense emotional need to talk to me. (Not me personally, just the unfortunate person they've currently latched onto). It's usually a sign of an emotional attachment that has everything to do with their emotional needs and the emptiness in their lives, and nothing at all about our interaction, or me
