I want to kiss my roommate to see what happens, how/when should I do it?

So we met at a shared flat and now we both moved out into another home for just us two.
bc we get along great and got sick of the other dude.
And I don't know we agree on everything and he's told me more than a few times that I'm cute or a 'little angel' and so on.
And you know there's these awkward stares when we talk about romantic topics but we both don't act bc we live under the same roof
But i think sparks would explode if we ever kissed so I really wanna give that a try, only hoooow
