Guy visits the doctor and tells him, "Doc, I've got a sex problem. I can't get it up for my wife anymore." The doctor tells him, "Bring her back with you tomorrow and let me see what I can do."
The next day, the guy comes back with his wife. The doctor tells her, "Please take off all of your clothes and lie down on the table." After she's lying there naked, the doctor walks around the table a few times, looking her up and down and all around.
Finally he pulls the guy aside and assures him, "You're fine. She don't give me a hard-on, either."
Little Johnny's parents got divorced. One night Little Johnny walked past his mother's bedroom, the door was open, and he sees his mother lying on her back playing with herself, saying "I need a man... I need a man..."
A few nights later he walks past her bedroom again, the door's open, and he sees his mother with a man on top of her.
Little Johnny runs to his room, jumps on his bed, pulls down his pants and starts playing with himself, saying, "I need a bike... I need a bike... "
His dad came home from a week-long business trip to find Little Johnny with a brand new mountain bike. "How'd you get that, son?" his dad asked. "By hiking" was Little Johnny's reply. "Hiking?" his dad asked in surprise.
"Yeah. Every night last week Mr. Johnson came over and gave me twenty bucks to take a hike."
