how to tell my husband

Sorry it has been so long. Life has been busy.
To answer some of your questions, My husband is above average. His cock is as large as any other men I have seen. That's not an issue.
As I read your comments and as I have had an experience, I have realized I am deeply in love with my husband, but I am starting to feel old and unattractive. Hearing I am beautiful from my husband is great but to hear it and experience it from someone else lights a new fire.
not just hearing it from another man, but to have another man so overcome with desire for you, that he fucks you, uses your body to relieve the sexual need you've created, can be intoxicating.
