Masterbating In Public Shower?

I'm 16 male and currently on a camping trip in the UK, this morning I was in the showers on the campsite (there are several separate cubicles but the dividers don't touch the wall or the floor so you can kind of see the feet of person next door) anyway I was showering and I noticed movement in the coner of my eye - it appeared that the person next door was mastetbating as I could see a weak reflection in the wet floor - I could be mistaken though he was heavy breathing :/ anyway when I left the cubicle he was outside (I think he was waiting for his mate to finish showering) he was about 30 I guess. The thing is I haven't had a good w*** for a while and really want to, is it a good idea to do it in the showers of a campsite, what if people catch me what would I do? Any suggestions? Any tips on how to keep it on the down low?
