Often guys get a surge of chemicals after orgasm that makes them sleepy. So they're simply not chatty but in recovery mode.
I usually go for a little cuddle and remark how much I enjoyed the session, leave some time and talk about what they have on for the rest of the day and if time is nearly up hint at a shower.

If they came early in the session and might recover for more I simply do hugs and strokes and give appreciative noises if they're touching me.

On the way out and or getting dressed might initiate conversation about, weather/holidays/local events or current affairs. Nothing too personal.

If they don't respond then they're just not chatty and wouldn't worry about it. Don't blame yourself.

I usually don't strike up conversation after! i much prefer just laying there saying nothing to be honest and when this happens they either try for a conversation or leave ! I'm not sure why I do this! I don't mean to be negative or anything ! I guess it's just laziness ! Talking to clients take effort cuz most of the time I don't care about what they are talking about !  But if they have loads of time left i ask them if they want a massage ! It's much easier than talking and pretending to give a shit  however I do try

This is one thing I never have a problem with as I can talk for Britain

I usually ask them what line of work they're in, if it's the first time I've seen them. If they don't seem to want to talk about that then I'll just babble on about any old crap, including politics and religion!

I'm the same, I'm a bit of a gab. I usually just ask how the rest of their day/week is looking. Some men like a chat, some don't, I don't take it too personally so long as I know they've enjoyed themself.

I'd rather the silence than the personal questions, but I don't mind a chat. Music and films are favourite especially if I've mentioned a gig or film festival on my blog, plus local goings on and gossip/general whinging (which is easy if you're in a small town ).

Some guys just don't want to talk much they are enjoying the feeling of being satisfied so a cuddle and a shoulder rub helps. sometimes we'll make small talk it just depends. I'm usually find but change the subject if they ask personal questions. Some ask about boyfriends,what I do outside this,my real name  etc slowly getting more personal but I can usually get them to drop it quickly enough. I just ask them about things they like,music,video games whatever

Sometimes I cuddle into them, other times I ask them if they want a massage. If we do chat, I try and steer clear of anything personal or revealing. Otherwise I'm happy to talk about anything really.
