As do I, so far I have had the pleasure of doing this 20 times. I agree it is hot and sexy to know my wife makes other men cum either with her pussy or her mouth. Along with enjoying the wife's creampie there has been a few time I have cleaned off the other guys cum covered cock. For me this is not about being submissive or playing a cuck role it is just how I enjoy participating in our MFM encounters. It was not always this way it was just something that started as a curiosity for me and then evolved. I also believe it was a factor in me having in interest in sucking men off.
