if it's important to you, that's why you have friends and family.
i'm sure as an adult you can handle not fondling other adults at work, because even if you think 'it's important', you don't know what kind of space other people are in and how they feel about you touching them.
Touching is a physical action. You touch a cup. You touch a dog. You touch a touch screen. You touch someone when you shake their hand.
Roughly, you can't fondle a cup. You wouldn't say you fondle a dog, and you won't say you fondle friends and family.
(And I do know spaces my workmates are in... as much as family and friends, so should you if you are able. Human beings matter, a workplace is more than money)
