Cruel Celibate Wife and her subchub husband

I am a 66 year old, submissive beta male married to a 65 year old woman. We are both fat and ugly on the outside. I recently came out to her and asked for permission to explore sex with other men like me. She doesn't like it, but since she has zero sexual desires for me, she'll support this lifestyle. She knows she is cruel to me, but we agree that celibacy for her and homosexuality for me works in our marriage. She will never again, suck and fuck me, and thats okay, I prefer dirty sex with dirty old men now.
