Appearing on This Morning on Tuesday, Dave revealed he started his collection and introduced Shawna to them after meeting her on a dating site.
It wasn't long before the couple began having sex with the dolls together. Shawna told Phillip Schofield and Amanda Holden: "I was really interested because they looked really cool.
"I started looking down their shirts as I wanted to see everything. It's kind of like a threesome without anyone getting hurt."
Shawna admitted to adding her own doll to the collection, a 'male' called Terry.
When a confused Phillip asked how it works, she replied: "Terry is always ready. He has three different parts!"
