I think the people on here are quite chatty.. :P
As for the pelvic floor excersises.. if you get you wife to lay on her back with her knees up and get her to squeeze her butt and pull in her tummy button to her back at the same time.. hold it for five secs and do it five times that should make her as tight as a virgin and have cntrol like you wont belive.. ps if your wife has had kids she will know the excersise as you are given them after the birth of a baby ;) hope that helps you out hun :P
