Ive Always wanted to try it has anyone else?
Yes I have/do. This is a very sensitive activity and the major key is communication with you SO, and being respectful about their needs/comfort.
my girlfriend was going to allow it when we had our kid but due to unfortunate circumstances that probably isnt going to happen
I was going to as well, but like geauxblue, my wife had an unfortunate circumstance and never got pregnant again.
