I am wondering as my DH drinks and smokes. Not a huge amount like binging but a steady small stream.
He doesn't eat very healthily but I am slowly trying to help on that front.
I wouldn't want to ask him to stop drinking or smoking.
He knows the risks and must make his own mind up.
He will be going for semen analysis soon so I guess that will either show him he needs to change or confirm there's no problem
