I really like your bond with your little one!! but now, I think you should let her handle him... after all, she has more stake on it than you!!

I suppose you just give him little space.. and probably he'll realize your existance as well haahahaahahaahaa Good luck buddy

Maybe you should have an affair with my penis and make yours a little jealous....

Don't they say 'three is a croud'? Sounds like your wife is getting a very close friendship with your penis. It can happen when there is a new friend in the picture one of the two originals feels left out. ... But perhaps you can play the jealousy card. Didn't she also bring someone into the picture? Try to get friendly with her vagina. Try to get a close bound with her and maybe your penis will get so jealous that he'll see he has neglacted you and will try to become your friend again.

Of course you could also just enjoy the time you spend as a foursome.
