Any specific size?

A lady's husband dies. After a couple of years, she gets lonely and decides to put a personal ad in the papers to try and find a new mate:

"Single woman looking for a man who: Won't beat me, won't run around on me, and is great in bed.."

The next day her door bell rings. She answers it to find a man in a wheel chair with no arms and no legs.

Woman: "You're not here to answer my personal ad, are you?"
Man: "Of course...is there a problem?"

Woman: "You have no arms!!"
Man: "Then I can't beat you!"

Woman: "Ok, but you have no legs!"
Man: "Then I can't run around on you!"

Woman: "Well....are you good in bed?"
Man: "I rang the doorbell, didn't I?"
