Sex position for bad back ?

Hi all

my partner can't go on top for to long due to having a longstanding lower back problem

looking for ideas or positions to ease her pain ?

Hi there, this Bondage Boutique Sex Position Enhancer chair may be useful as it reduces muscle strain :)

I have hip problems from difficult pregnancies so going on top is really painful for me. We invested in the Liberator wedge and it really helps relieve the pressure in all positions.

I second the Liberator Wedge, not the cheapest but so worth it!

We play with a couple of friends where the woman has a bad back, she finds face-down doggy most comfortable.
