Public displays of affection - better known as PDA - are not great if you're a member of the public. But if you're a loved-up couple, holding hands, kissing, and holding each other in public is all part of the fun of courtship. Nobody is suggesting you start getting hot and heavy at the local shopping mall, but a little escalator kiss or an arm around the shoulders never goes unappreciated.
Women enjoy when a man is willing to be affectionate in public with them. It shows they're proud of the relationship and don't care who sees it. A man who is physically cold in public is not any woman's idea of a dream man. If you feel like you've been holding back, why not get initiated with a bit of hand holding. Trust us, women love it!
