I prefer to put it on while it is still wet, and wear it until it is dry. Each squelching step reminds me of the 10 seconds of pleasure I encountered earlier.
Either/or I suppose. I mean, it really depends on the situation at hand. If the situation demands that I go somewhere where the sock is immediately needed then yes, you have very little choice but to put it on. And of course that slippery sensation that coats the skin of your foot for a while is quite satisfying.
But also it can't be said that having a nap at 11:30am directly after your ejaculation in front of the TV, naked with the windows wide open - having done absolutely nothing productive since you awoke at 7am - and then waking up again after 2pm and putting that sock on over your foot and feeling that hard, crusty fabric scrape an scratch its way across your skin is also fantastically satisfying.
There's a tingling in your balls either way. So I'm good.
