We prefer to limit the drama in our playful relationships. We generally look for stable committed couples. I suspect that most people who have gone thru this surgery have struggled alot. So it would probably be a disqualifer.
If a friend were to struggle with it, the situation would be different and so would be our reaction. We would want to support any friend going thru tough times. However it would probably be mostly as practical and emotional support.
We don't have many rules, but we always use condoms for penetration. On one occasion a condom broke during anal. As soon as I noticed I stopped. The woman I was playing with would have continued, but my wife and I live by the condom rule.
