Asking the experts

So I'm stuck. I'm a closet bi, and there are moments where I really just want to pleasure my best friend and just put him in my mouth. I don't think he has any gay thoughts or intentions (he has a wife) but i feel like he may let me. He has a very flirty demeanor by nature, and likes to goof, so everything I joke about being gay or whatever (my way of staying in the closet) he just laughs or just doesn't say anything.So any thoughts on how I should go about this?
