Like to try cuckolding

I Like to try cockolding. Is it okay to find a bull that have bigger penis than mine?
I have not told this to my wife yet.I have been watching cuckolding porn and i’m imagining what if there was my wife with that man..
I can’t stop thinking about it now.
Now i only wanted to see her face when a big penis enters in her first time.
Need to say.. i’m from sri lanka (an asian country).
