This young fellow is about to be married, and is asking his grandfather about sex. He asks how often you should have it. His grandfather tells him, "When you first get married, you want it all the time, and maybe you'll do it several times a day. Later on, sex tapers off, and you have it once a week or so. Then as you get older, you have sex maybe once a month. When you get really old, you are lucky to have it once a year, like maybe on your anniversary." The young fellow then asks his grandfather, "Well how about you and grandma now?" His grandfather replies, "Oh, we just have oral sex now." "What's oral sex?" The young fellow asks. "Well, she goes to bed in her bedroom, and I go to bed in my bedroom. She yells, 'Screw you,' and I holler back, 'Screw you too!'"
