ME, My husband is deathly afraid of rejection. I would even say irrationally afraid of it. There is no basis for this fear, as I could count on one hand the times I have rejected him for sex. He literally cannot stand the thought of being rejected and would just as soon not initiate at all--and face my wrath--than go through a possible rejection.
NOPkins had an idea that a schedule would work for a couple like us because it would take the scariness of initiation out of the picture. Someday we may actually be able to try this!
