Being Bi and dating Bi (discussion post)

Recently I have started talking to a new guy. He is amazing and really makes me happy. The other day one of my really good friends (who happens to be a gay guy) was over and the three of us started talking. Well it turns out that the guy I am talking to is actually bisexual as well, but has not told anyone about it before. He likes both me and my friend, and wants both of us. In the past I have told my friend that I would share with him if I found a guy we both liked. Well that has now come true. Next weekend both of them are supposed to be staying over my house with me for my friends birthday. Not entirely sure how things will work out yet. In the past I have been with a guy who has allowed me to have my girls as well. So I feel I should not restrict my guy from having another guy. Does anyone thing it is weird or wrong that I am sharing my guy with another guy? 
Not to mention the guy he wants is fully gay. And I think i may also be falling for the gay guy, who I know has dated one or two girls in his life so I am not sure what to do about that one

 
When me and my friend talk about the guy I get extremely happy, but when I think about just my friend or just he guy... i am happier thinking of the friend...... not quite sure what to do in this situation.
