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."
A guy was talking to his buddy, "I learned a very important life lesson today. I'm getting married in a few weeks and I went over to my fiancee's house to look at the wedding invitations with her mom. Her mother's really sexy, and as we were looking at the invitations, she started rubbing my leg. Within a few minutes she leaned over and asked me if I'd take her upstairs and fuck her. I immediately got up and walked out the front door. On the way out I ran into her father. He smiled and told me 'You passed our little test, son. Glad to have you in the family.'"
