When I was young (teens to early 20s) I self identified as gay. And I can remember not being very convinced by the existence of genuinely bi people.

Then I fell in love with a woman, still happily monogamously married to after many years.

These days I would self identify as human. But I guess you could call me bi: I still find attractive men attractive.

I'm not sure what I would seek these days if I were single.
