Lisa: 'I was sexually frustrated'

Lisa has admitted that she struggled to keep her hands off boyfriend Mario when they shared the Big Brother house together.

The bodybuilder confirmed that things often got steamy under the covers when the lights were out at night.

"It was very frustrating. It was very, very hard. It was extremely hard," Lisa explained. "Me and Mario normally share a massive bed, so to share this little bed together - we had to go side on. Anyway, the extremely hard bit, which I'm sure you want to know about, it got very hot, very steamy and the sparks were flying. It was very tempting! There was a little bit of spice, but you'll have to use your imagination."

Asked how far they went, she replied: "Far enough! Ha, ha, ha! As far as you could within the means. The trouble is, that you're in a little bed, side on and there's an occasional slippage…ha, ha, ha!"

Lisa also claimed that fellow housemate Rachel had caused problems for her relationship in the early weeks.

"She is very, very confident and way too in your space and that's where the problems came in," she said. "I wasn't sure if it was me and Mario, or Mario and Rachel. She kept crowding us. I felt uncomfortable with that. She was around Mario too much. She was annoying. I think there's more going on with Rachel than she lets on."
