Let me ask you a question. How much do you love your wife? No, I’m serious. Seems like you love her a lot. Are you head-over-heals in love with your wife? Do you cherish her? Adore her? Believe it or not that could be your problem. When a man falls in love truly, a predicament that is maybe less common than you might think, his testosterone level actually goes down. That can make it more difficult to maintain an erection. I saw an article ( http://www.news … al.net/?id=1265 ) on that while googling the topic, because it was happening to me. It took me 25 years (including 13 in a marriage and another 7 in committed relationships) to find the right woman for me… a woman that I REALLY loved, personally, emotionally, and physically. Making love to her is sweet and deeply emotionally moving because I am so very much in love with her. It’s the strangest thing. We can be making love, and she starts saying "i love you so much" and many other sweet, loving things and I begin to feel the emotional connection, and it becomes more difficult to stay hard. My girl, now my fiance, is the perfect body type for me, and she turns me on like no one ever has. I never had a problem staying hard with my ex girlfriend… but I did not love her this way. Hmmmm… interesting huh?
So what do you do about it? Tough to say. Slow, emotional, loving sex can be very nice. I like to go down on my girl when I’m feeling very loving. Doing that fulfills me emotionally, but it also does a pretty good job of turning me on again. That works for us. Another thing that seems to eliminate the problem is to have hot steamy aggressive sex. The animal in you overpowers the love I think… you’re just having great sex with a hot babe who happens to also be Mrs. Right.
Also, try to close your eyes and enjoy the feeling of trying to get hard again. Breath, smile, relax and enjoy the process. That helps me a lot too. Dwelling on it or worrying about it is a waste of time (though it’s a natural response in our sexually messed up culture).
Anyway, hope that helps. Good luck.
