Knotted rope

One day a young cowboy and cowgirl decided to get married. After the wedding, they left for their honeymoon. While driving down the road, the new bride sees two cows having sex.
The new bride asks with a sly grin, "What are they doing honey?"
The husband answers, "They`re roping!"
She replies, "Oh, I see!" while trying to hide her knowing expression.
After a few more hours of driving, they pass two horses having sex.
Again the bride asks, "What are they doing honey?"
The husband answers, "They`re roping!"
She replies, "Oh, I see!"
Finally they arrive at their hotel. The couple washed up and started to get ready for bed. When they got in the bed, they started to explore each others` bodies. The bride discovers her husband`s privates.
"What is that?" she asks.
"That`s my rope," he answers.
She slides her hands down further and gasps, "What are those?" she asks.
"They`re my knots," he answers.
Finally the couple begins to make love. After several minutes, the bride says, "Stop honey, wait a minute!
Her husband asks, "What`s the matter honey, am I hurting you?"
"No," the bride replies, "undo those knots, I need more rope.
