I consider myself to be Bi.
I once heard someone phrase bi sexuality as being like one person...but having two sexual spirits in your body. I was able to relate to that a bit...and it helped me figure things out.
There is a spectrum for sure. And I think it's normal to swing one way or the other at times.
Certainly the things I find attractive in a partner in terms of personality and character have very little change from gender to gender. But physically it's different. And the way I behave and felt romantically felt unique depending on the gender of said person...
I have no idea if any of that made sense.
