The thing you need is a glass shaped p***s thats solid, this way when you sqeeze on theres no give and when you get good at you should be able to lift yourself up without it falling out, I was told about this years ago with somebody I worked with his wife had one, he said it was the best thing ever, and that was after her having a baby problem.
Good Luck
tnx alot but doesn't tht keep it the same way it was with the penis?
Nothing else really you can do. Keep doing your kegels. You can also buy you a fake penis (close to your man's size) and practice squeezing it in your spare time.Practice makes perfect.
