Anal ¿yes or not?

M
Does it hurt?
How's everything down there afterwards?
Does it expands? 
Does it really feel that good? What do you feel?
My guy always asks, he's like:
"tonight?"
"you're clean girl nothing will happen"
"they say it's really good for you too"
Or "just a finger you'll love it I promise"
So I'm curious, but not if it feel better the vagina... It's better?
