“I can’t move much in bed, but I burn 500 calories a session –- it’s great exercise just jiggling around, we have sex up to seven times each day’’ Potter said.

 “We love foreplay and massages and, as well as full sex, I pleasure Alex, too," she said. "My bed is strengthened and, although I can’t buy sexy lingerie, I drape a nice sheet over me.”

She said, “Within the first day of being back together we had sex six times in 24 hours,"

“Even though one of Pauline’s legs weighs more than I do, we’re able to position her body to make sex enjoyable for both of us."

Alex, who weighs just 140 pounds, does most of the work in the bedroom.

“It’s really dangerous for us to have sex because at any moment the bed could collapse and one or both of us could be seriously injured or even killed from the impact".
