A wise choice; it shows you both trust each other that much. Hope you have a long and happy time together 'till death shall you part.
Looking at hot bods is how human beings are *wired*, quite literally, and especially so for guys. Trying to avoid the instinct entirely is hopeless and doomed to fail...but you CAN put a 'mental roadblock' to make sure that looking is ALL you do.
So again, good job for coming up with a realistic policy. The challenge now will be sticking to it. Best of luck to you both!
