re certainly right about the fact that stress can create
performance anxiety. In fact, the idea of sex as
PERFORMANCE rather than pleasure, is a major factor. The less pressure you put on yourself, the more you can relax and, together with your girlfriend, talk about possibilities. A hard penis isn't necessary for great sex. Creativity and attitude are much more important. I recommend an excellent book: "The New Male Sexuality," by Bernie Zilbergeld, Ph.D.
