Ways of affection? PLEASE answer:)?

My boyfriend and I are both 15, both christians and don't want *** until after marriage. We are both indecisive people so were having this game that whoever says "i don't know" has to do something bold and the other person has to think of it. He has lost 6 times. Haha. So far I have...he has to put his arm around me without me asking first, he has to hold me when were standing up somewhere, he has to kiss my cheek and he has to say something sweet to me in person. So thats four. Can you think of two or more for me(by the way we have already kissed before) Thanks! By the way...nothing that goes too far.
