He's gay. Or at least bisex
I always get the same impression too. He’s addressed gay rumors during Instagram Q&As and states that he’s 100% straight. It doesn’t appear that there’s any photo leaks.
 
Also he is friends with Ricky Martin’s partner. So yes, he knows Ricky martin. He’s not gang banging them bahaha his gf is there to take care of his needs for that lol
 
His brother is gay though. He was asked if he had a single brother on an insta ama. He answered the chick who asked with “yes, I do! my brother is single af and extremely handsome but...he likes the guys so you’re out of luck”

So he’s much like Chris Evans, closest you’ll likely get to see either of their dicks is by proxy with their brothers’ dicks haha. And that’s provided they share penis genetics and aren’t like me and my brother where in that arena we are quite different: I’m hung like a horse and he’s just average haha.
