I would put whoever I wanted to date, regardless of whoever I had feelings for; I was neither gay or straight, but I specifically wanted to date men, so I put straight to get the right attention.

There have been times where I contacted someone and they told me they didn't date bi women, even though I was looking to date a guy. So be careful of what you choose. If you are looking to date women only, put gay, so that way you don't get contacted by men when you're not interested in men at the moment.
