I was with a prostitute who was about 25 or 30 years old. She was nude. I disrobed and displayed my body to her. She said that she didn't think I would be able to satisfy her. However, I was sure that I could do so, so I talked her into letting me try. We proceeded to have intercourse, even though she was still rather skeptical at first. I satisfied her and the dream ended with my having an orgasm.
