I think lube is the key.
Light covering of Vaseline on the aneros then water based lube over that plus 5ml up your but of water base.
I thought you did not need the Vaseline but it makes all the difference!
Make it 4ml water base and 1ml silicone + the Vaseline if you want to sleep with her all night long and longer.
As long as its not a vice or syn......
k, thanks for the tip, i love sleeping with her....
lube always seems to be the key
