It depends on circumstance. Reaching out to him for some PDA occasionally or in private is great. It can be a little inappropriate in a lot of public circumstances, particularly for men. If you are in public and he doesn't respond warmly to your PDA, then don't take it personally.

Don't worry how he will react, if he reacts negatively you know that he's not on the same page as you. Guys around your age are much shyer than girls your age, so make your move, don't wait for the chance, he's your boyfriend you always have chances around him :) x
