Phone Etiquette

Whats the appropriate number of seconds to pause between numbers when giving out your phone number without being insulting? I know if I go too fast I'll get a "whoawhoawhoawhoa." But I feel if I go too slow, it's worse...after the first 3 numbers I usually pause, and I wait for some sort of affirmative noise from the other end of the phone. If I don't get it right away, I might wait a few seconds. But then I picture the guy on the other end going "what, this guy thinks I'm fucking retarded? I can't keep up after 3 numbers - what is he, fucking better than me???!!" and then he'll spit in my cat foo young. I dunno.
