here is my theory on this. Our 1st experience was with a friend my DH had been friends with for over 10 yrs. we had joked about it on and off and he had seen me undressed one new yrs eve when I was drunk and I only weighed 88 lbs and then again when I was my largest ever at 155. Ok I have digressed here. The point is if you have a good strong relationship then it can work great, He had some personal issues and we driffted apart unfortunately.
