Threesome experiences?

I want to have a threesome with my boyfriend and another guy but i feel like it can get awkward in reality comparing to porn. How was your experience? I wonder if my bf would be willing to with his best friend i got the impression he does but i dont know how to even ask him! we were in his best friend's bed (guy) and the bestfriend walked in covered in a towel and my bf made a joke asking if he had handcuffs so they can pin me and see my reaction... yesterday we had sex in the same room with his bestfriend in it and my bf was encouraging him to do it with his gf in the same room too. Are those hints??
