None of the women I've ever been with wanted their asses eaten, and I also never requested it, as it seem disgusting to me. Zero interest in it.
The only ass play I've been interested is anal intercourse, but only 2 women I've been with had any interest in it. One could only take about 2-3 inches of me inside her despite lots of foreplay and tons of lube and patience. The other said she loved anal and would be open to it the next time we got together, but unfortunately, circumstances prevented that from ever happening.
