DH & I just tried out sex whilst I was using my electronic pelvic floor toner (the one that wraps around your thighs & bum - no brand name in case the thread is pulled) to see what it felt like.
It's not the sexiest of costumes & we had to be careful not to disconnect the electrics, plus be a bit creative with positions.
He felt a little more sensation, nothing major. But for me it was amazing! Such intense orgasms (clitoral & penetrative)
If you've got the kit I thoroughly recommend trying!
