Hi there,
I presume that the 'hand habit' that you're talking about is masturbation.
Masturbation, when done when you're sexually excited is a healthy exercise. Don't do it out of boredom; or when you have nothing better to do.
You need to find better ways of handling your time and keeping yourself occupied.
Lastly, masturbation per se, is not going to cause any problems in your marriage. But the thoughts associated with it can.
Good luck.
