I have anal sex with a man, I am the top.I wore the condom when I entered his anus. When we ended sex, I lay down and wiped my body with a towel, then I touched my penis, there was no condom on the penis, and the condom was between my thigh and waist. During the sex and after sex, I didn't feel the condom falling. I think the condom fell when I wiped my body. I was worried that the condom fell during sex, but I didn't notice it. Does this exist?
