''People are getting more adventurous in how they do things and where they do things,'' Ms Davidson said.
As popular culture was becoming more explicit, people were being more adventurous trying to match movie stars' exploits and many were overestimating their body's flexibility, Ms Davidson said.
People were experimenting outside the bedroom - such as dining tables and kitchen benches - resulting in injury when the furniture collapsed under the weight of the activity, she said.
The stories of the injuries were shared by clients, and among physiotherapists, although personal details were not disclosed, she said.
Of the claims made nationally in the past six years, men accounted for 70 per cent. In Otago and Southland the gender percentage was the same.
Ms Davidson said men were overrepresented in the statistics because they often acted without thinking of the consequences or attempted to prove their manliness.
