Erectile function is highly dependent on psychological engagement and mood factors. A man must concentrate and be relaxed, yet be highly aroused in order to achieve and maintain a nice stiff erection. After ten relaxing days on your honeymoon, where you no doubt had little stress, worries or care, you came back to the real world and your penis promptly betrayed you. It s not uncommon. So don t be overly worried about it. Your spouse can help you with your erection by using oral sex as foreplay and manual techniques as well. The penis functions better when multiple modalities of tactile stimulation are used to arouse it. Alternating between the mouth, the hand and the vagina for stimulation, the penis tends to do better and function better in general. If you are uncircumcised, you have an even wider array of tactics available to you. Your spouse can use the foreskin to stimulate you in a multitude of ways. With the foreskin retracted, your glans becomes a repository for highly sensualized stimulation. Your spouse can use her imagination to help you maintain erection by manipulating your foreskin with great variety. While she does, be sure to lie back and guide her with your words. Also, before you penetrate her, be sure her vagina is well lubricated. This will make it easier to penetrate her even if your erection is not at maximal tumescence. Try various techniques and see how it goes. I m sure you will improve if you set your mind to it without worrying too much. Feel better and best of health to you both!
