Your body is telling you something. There is a natural reaction of the anal sphincters to reject anything trying to gain admittance. They forma one-way valve. You overcame this autonomic reaction through care and trying. Now, however, it has kicked back in. I do not know why but your body does. It is the anal equivalent to secondary vaginismus and it will not easily be overcome.

Do a search on anal sex and find some of my posts on long term consequences.
