I used to tell everyone. Then I stopped because sometimes coworkers or some friends see it as your main feature and talk to your stomach, looking for your bag.
I no longer tell anyone unless I feel they may see me naked. Dating many times is just casual encounters, just hanging out, dinner, movies. But if you meet that special someone, it's better to tell him or her if you think the relationship will progress to an intimate relationship. If someone asks you what the crackling noise is,
they keep hearing... tell them it is a candy wrapper in your pocket.
