Totally agree, his gift to my wife and myself goes beyond his cock. I wouldn't say I worship his semen, but in 4 years of very regular encounters, not once has his seed been wasted. I make a point of showing him how valued it is to myself and my wife. If he can give her the gift of mind blowing climaxes, I think its on me to thank him in return by showing him how valued his sperm is. I can't imagine him ever desiring to have sex with another man, but as a cuck I think he feels his role as a bull, is to embed his role as the alpha male over myself so we all know our place in the room on the night.
