Ya, many of the boys I've gotten were supposed to be sexed! The accuracy rate is allegedly 90%. While I find that true over the grand scheme. I have even gotten 100% males on one batch of 2. 
You have a boy there, IMO. At 16 weeks they would be starting to red up. But my hen over 1 year doesn't quite have that comb and waddles. It should be a bit closer to your red in size.
Also, I was thinking 16 weeks would be early for an Orp to start showing signs of lay... and though late for some breeds to start chasing and mounting, probably on par for a generally slower developing breed.
Start making your plans now, that's a boy and he's pretty too.
In paying attention, I think I can make out saddle feathers though hard to see in that pic. The hens get what I call a hen bump. Where as the boys saddles kinda part and lay down on their back, sometimes dangling over the wing just a bit.
Hoping for a good home.
Also no shame in letting him feed someones' family if you can't find a nice home. Plenty of us do it as quick, humane, and dignified as possible.
