I have to kind of agree with Malixer on that one. I think it's a huge trial and error kind of thing and once you look past sexual orientation it's a lot easier to find someone you can just click with. In my life I've had a pretty good mix of both male and female as my significant other and in all honesty, it was all about clicking with someone and less about their gender. In order to get in a relationship I just need that clicking with someone because I do tend to get bored really easily. Currently, I'm in a relationship with another woman and we just hit our 8 year mark so there has to be some sort of click there. And if you ask us both about our sexual orientation we'd both say bisexual.

My advise is to worry less about labs and worry more about how you connect with people. Once I let go of worrying about what I was I got to enjoy myself and my partners a lot more.
