Wow, I cannot believe at this time of modern days, we still have debate on this....

Other than religious reason, why would you want to hurt your son this bad physically (proven a trauma even as baby or kid) and mentally (smaller penis when he grows up)?

OMG...

Let the foreskin grow and when it hits to the time that is is blocking the penis growing, you can just roll the foreskin back, a bit painful but after one time the foreskin will never get back to the front blocking the growth or pee.
