I have a friend who is in the Royal Navy a Submariner. When is on shore leave he can't leave it alone but when he is at Sea often for weeks at a time in close proximity to others you just don't do it.
He told me very quickly you get used to it.
The less you do it the less you miss it.
Having said that he's in his mid 20s so on the downside the wet dreams and blue balls
Late teens have it harder. (Fnar)
