Idiom: "Under"

Another discovery led me to a shock…
I have this photography sharing site and someone added me, like 2 years ago. He’s hot, model type of guy, great body and really cute. He was my crush from then on.
I was with a close poz friend and sat beside him while he was browsing his Facebook. Come to my surprise, that hot guy has another account. Maybe his real one. And he was now the center of conversation and now.. He’s also poz. Wow. Cases are really now increasing tremendously. I can’t them. World just keeps going smaller and smaller. 
Now I wonder, is he “under” or what?
“under” – you know what I mean… 
I hope he’s nicer now.
