That makes no sense at all. Your claim that everyone is either absolutely 100% totally heterosexual in all ways at all times in deed, thought and feeling or they're homosexual just doesn't match up with reality. It's a false dichotomy.
Maybe you should just accept what I am rather than pretending I'm something else so that you can fit me into your false dichotomy.
If I was homosexual, I would say I was homosexual. If I was heterosexual, I would say that I was heterosexual. If I was 50/50 bisexual, I would say that. I'm well aware of my sexual orientation and I described it accurately. The fact that reality doesn't fit into your false dichotomy isn't my problem. I don't need to accept your error. Sexual orientation on the homo-hetero thing is very obviously a spectrum.
