How far back does foreskin go during sex?

[jakejohns]

As the penis slides through the vagina, whats the maximum retraction of the foreskin?
Once the hole head is retracted, does it go further then that and retract more?
Or does the foreskin just move up and down on the head?

I think it depends on the penis in question, and how tight the vagina is...kinda like jackin off, if you have a loose hand around u, it won't retract much, but tighter, it may fully retract behind the head and stay there until it goes soft...
