with any type of film,
the stop and start alot.
so they try as best as possible to get tem down to make the movie better.
i think that cos they do it soo much, i aint sure if this is true but im just putting it out there, they get use to all that pussy and stuff that it takes longer for them to pop it up,
i mean if u go to a nude beach, u don't see all the dudes with rages on, (even if the women aint the greatest)
but for dudes like us when we know were getting it with someone like a WG it makes us jump up and like billyhamlan said u get to the door and ur allready up and running.
thats what i think anyway.
