Reconcile yourself to knowing that you like both. I do, but for me men are for getting off. Women are for a more emotionally stable long term relationship.
Before I sound like an expert, I haven't been able to maintain anything resembling long term with women. But that's where my heart lies.
To me, men are for physical relief. We are action-oriented without attachments. Just get me off, that's all I ask. And I'll be happy to do the same.
But when it comes to romancing, sharing, longing, protecting, then women only immediately comes to mind. I'm not saying it couldn't happen between another man and myself, but that's not my aim at the moment.
Being realistic, women apparently aren't my aim at the moment either, at least not for long term. I still date women, but have never dated a man.
In any case, you are far from alone. It's very difficult to put such things in words, and I may have failed miserably. But I hope some semblance of similarity is there.
