boyfriend may be bi...dont know what to do

Hi, I'm in a really strange position and I don't have anyone to talk to about it. I am a 19 years old and I have been with my boyfriend for 6 years (on and off). A little over a year ago we had a talk about how he always questioned being into guys. At first it made me a little sick to my stomach thinking I may be in love with an obviously unavailable guy. I put my feelings aside and listened to him and tried to help him figure it out. We are very open with our sexuality or just in general and have bought a strap on to use with each other. The topic never really came up into a huge discussion again for a while, until I found out he was watching gay porn. Its not the first time he has done this but for some reason it just really bothered me. We talked about it again and I told him I needed to know because it was really making me upset. I want him to be happy and I don't want him staying with me and regretting something he never got to do. I am completely comfortable if he was to be bi, i even told him that if he wanted we could find someone to have a three sum with us..maybe to let him explore? im not sure that would be a good idea i dont know if it would be a good idea to let him go to explore because he wouldnt...any advice?

he told me how he no longer feels sexual feelings towards girls, and that if we were to ever break up he does not know if he would ever be able to be with a girl that he thinks it would be easier to be with another guy. In our past, I was really over protective with him and other girls and feel like I am the reason he know feels this way. I'm wondering if its possible for a gay man to get an erection every time he sees his girlfriend(me) and have sex all the time. I do not know what to think, whether hes bi, or just open to anything, or gay. I am sure this post makes no sense but Ive never said it all out to anyone.

please help!!

Ha.

"someone open to his questions and help him explore."

This line is pretty hard for me to swallow.... Go to Boston and let him explore?????

Other then that I have no clue as to how to advice you. Sorry!!

Really??

Will you be comfortable if he wants the experimentation of the threesome to be ongoing in your relationship, if he ends up really liking it afterwards?
I think you should cover every aspect of what you would feel in this decision also, and not just cater to his feelings, which might just end up being the beginning of the end of your relationship afterwards anyway. Just a thought.

I don't know. I do love him and want to be happy but I also want him to be happy and not have any regrets. the only thing is...neither me or him know if he is truly bi or gay

That's more or less what I said in my post.

You don't work for Shady Records do you?
Perhaps Interscope?

I think "she" is just looking for wang pictures via the internet that "she" will be able to carefully "screen" as suitors for her "brother".
