za churchmouse :Pretty much.....just thinkl how pretty much allmen start by accepting a finger, then two or three, then a cock, then maybe two cocks or a big dildo, then so many train to acept a hand, finally even two hands, then fisting right upm to thr armpit. A continuous progression.......dilating, dilating, dilating.......
