Satori, don't listen to ShitFace. As you may know, I am an expert on male genitalia and I have to say, I've only seen wrinkled balls only once before and that guy was a virgin. I must conclude that only virgin males have wrinkled balls. That must mean your room mate is a virgin! ShitFace is also possibly a virgin since he had no idea testicles smooth out after having sex! How scandalous!
