Absolutely, my hubby is much more attentive and a better partner since he became a cuckold. By not having to worry about his shortcomings and inadequacy in the bedroom he is a much better life partner in all other regards.
He has embraced his role as a cuckold and loves serving me and my lovers. Instead of being worried about his little dick pleasing me or if he could even achieve/maintain an erection, he is now much more confident as in the bedroom as he knows his mouth is what gets me off when it is just the two of us. When with my lovers he is attentive and loving and serves us both as he is directed. Sometimes he just gets to watch, other times he serves us both with his mouth, and some of my lovers enjoy my hubby's ass also.
DO NOT take this wrong!! The best dog I ever owned was a Lab named Kyra. She was one of a kind.
