Master and I have done some anal play in the past, but not anal sex where He has penetrated me. I have IBS and my illness is so unpredictable that it would make anal sex more trouble than it is worth. Master understands what it is like to live with a chronic illness, so He has never demanded it of me for U/us to have anal sex. I think that maybe if I didn't have IBS W/we might've have tried it, but neither one of U/us really feels that W/we're missing something by not having anal sex.
