I have a small penis, and in fact am also impotent, due to a long-time medical problem. I can masturbate, and have an extremely satisfying climax. I have found over the years that almost all females (I'm totally straight), are very easy to please through oral, and manual manipulation. This is almost a plus for me and the female, as I always make certain my female partner climaxes, before I attempt to. To me, the largest enjoyment of a sexual experience with a female is watching, and experiencing her ultimate pleasures. . .Hell, I can cum anytime, and just love to see and experience the female parts having their pleasures.
When I first became impotent, I was very down and thought life was over. When I finally took the initiative to acually confide in some close, female friends, I found that most of them prefer to oral, and manual, over being humped. So, I have only experienced a very few disapointments over having a small penis, that cannot get erect. My impotency is from severed nerves, and chemicals don't seem to help. However, my Dr. wants to try Cealis sometime, to see if that will help. . .It might, but I'm OK with things the way they are. I've had many of great cums from a female giving me oral. My life's experiences have given me the opportunity to concentrate more on giving, than receiving. Hope this helps. . .Mike
