he wont let me take pictures of him

The guy im dating hates having his picture took, I really don't know why, to me he's honestly the most beautiful man ive ever met. 
He also doesn't have any social media pages or anything and im starting to get a bit suspicious about it all now. He said his ex hacked into his accounts after they split up so he deleted them all. But that was 3 years ago. I wondered if he had possibly blocked me on Facebook to stop me seeing things so i got a friend to search but we found nothing apart from a picture of him on his brothers page. 
I don't see him that often coz of his work hours and since he moved last January i havent been to his new flat he really doesn't want me their and i dont know why? He closes up when i ask him about it. 
I can't help but feel like something is going on and i dont know what to do? 
Edit - i cant show up at his place as i dont actually know his address anymore! I just know the area he lives in which also worries me
