Dear Gio, Please get my book "Orgasms for Two" that is full of useful information for heterosexual couples. There are so many other pleasurable ways to share partnersex and orgasms beside a penis inside a vagina. If you wanted to get your wife pregnant, you would need to focus on coming inside the birth canal. Otherwise, the clitoris is a woman's primary sex organ for pleasure and it can respond to a wet tongue, a slippery finger or a vibrator. Continuing to put that kind of pressure on your cock is totally unnecessary. Yes, a cock ring will hold the blood inside your penis a bit longer, but I must tell you that ten minutes of fucking after penetration is a fairly decent length of time. Your wife sounds a bit sexually lazy to me. It's my belief that we are all responsible for generating our own orgasms. It's time for her to stop laying there expecting you to do all the work, and it's time for you to stop thinking your penis is the only way to get her off. Good lord, man, go buy a dildo and fuck her for hours or as long as she wants. Then after she comes climb on board and shoot your load. Betty
