At what point do guys want to shower with someone else?

Okay my question is for the guys. I just had my first shower experience with a guy and now i'm confused. We are fwb but now im thinkin he may want more than hes letting on. In my book showering with someone is normally left for those who have been together for a while and it is very intimate. What do you think? Would you shower with a one night stand or is this reserved for someone you really care about?
