First dance replacement ideas

I realize this may sound completely odd, but I need some help. My fiance has had some very traumatic experiences with dancing, so much so that he refuses to EVER dance (even playfully). The first dance of our wedding has always been important to me. Dont ask me why I couldnt honestly tell you. Just us dancing for the first time as husband and wife is a precious thing to me. But due to him being traumatized, he cant do this. Its emotionally very stressing and can cause him panic attacks. Does anyone have any good ideas for a replacement of some kind? Like some other special thing we can first do as man and wife other than a dance? (Btw it wont work if we do it privately either, he still has a reaction). If anyone could think of anything it would be amazingly appreciated
