Should me and my boyfriend show PDA at christian camps and retreats? PLEASE READ BEFORE ANSWERING... ALSO PLEASE COMMENT WHY YOU CHOSE WHAT YOU CHOSE

So my bf and I have recently started kissing and stuff like that, and we do LOTS of church retreats together (probably 1 every 2 months) plus a week long summer camp. Is a kiss or anything like that (long hug, etc.) inappropriate for christian camp? (We have already gotten this huge talk from my Youth directer on how our body is a temple and to use it wisely, and we should glorify god with our physical actions) But is it a sin or dishonoring to God to do stuff like that at camp or retreats? (not in the church, but in the outdoors and cabins)
