I'm sorry you feel pressured, it is your decision and yours alone.
I had Henri neutered when he was 8 months and there was no change in him. He is still a happy little energetic thing who every now and then still feels the need to assert his dominance over a pillow :P
I was worried about if I made the right decision too but he actually seemed happier afterwards.
It is your decision, please don't feel forced or pressured, either way I'm sure Joey will be fine
