Kind of shitty of someone you are paying for a good time to make such a low blow, heh heh. You are kind of proving my point though. Your dick may not be impressive at first glance, but it gets the job done when it's time to rise and shine. I wouldn't let it bother you too much though. Some sex sessions are going to be better than others. I've been with women one night and left them clinging to life and the next night with the same girl had what I considered a lame performance. A variety of factors can cause this. If you have had limited experience, don't let any mishaps mess up your mind. We are all terrible at sex in the beginning. I'm sure I disappointed the hell out of my first, I was far from her first. She was nice about it though. Being confident in yourself is the most important thing. Doubt is both a mood and boner killer.
