Greetings!

Hi everybody! First post here obviously. I've known I was bisexual since my teens, but now I find myself 32 and about three months away from getting married to a woman who expects total monogamy and, well, I'm just not sure that I can give up guys for the rest of my life. Especially since I've always been more sexually interested in guys than girls. And recently connected emotionally with a younger man, which makes me think perhaps I can have a full blown relationship with a guy...but calling off the wedding and hurting my fiancée is just such a hard choice to make! Genuinely not sure what to do.
