Glad that all turned out okay, and "Amen" to all Karlin wrote!
It took me forever to get my friend to have her two male poodles castrated. She thought she wanted to breed one of them but I encouraged her to look at him honestly and see if she wanted to continue some of his less desirable qualities (he's afraid of everything). Plus she wanted to breed with a maltese because her DIL wanted a malti-poo. I had to get on my soapbox about that! She laughed when one of them would hump her leg until I told her that he was showing that he was dominant over her. Then they started marking everything in her house and she finally said "Enough".
Neutered pets - male or female - always make better pets and are less likely to develop several different problems in the future.
You did good! Now give your boy lots of love and have fun.
