When I was young, I was telling my host that I do things in wl. But I didn't. He expected me to be active in the background because people claim their tulpas are.
I am not telling you that your case must be the same. Just be careful with interpretation of your experiences. And keep in mind your expectations affect your tulpa.
Well... from what I'm told bisexuality is being interested in either of the normal genders, so a tulpa of each of those two genders would fulfill both desires if need be
However, in cases where it isn't clear, try to consider what aspects of a response make it more likely to be the tulpa relative to making it less likely. Additionally, do keep personal biases in mind.

The brain generates all kinds of feelings, including your own - which you may think are strange at the time.

Making assumptions leads to inaccuracy, and has lead people to make "tulpas" they later realized were hollow projections of what they hoped to get out of making a tulpa.

It might take longer and the tulpa may be annoyed with you if you miss some things they say, but you can also freely explain that you aren't making assumptions because you want to speak with them rather than some projection of your own thoughts.

That said, if you aren't looking to necessarily make a tulpa, but just make some thing that you can call a tulpa regardless, feel free to make all the assumptions you want. You might make an actual tulpa or you might not, but it will certainly be faster.

And then you won't have to deal with the terrible and awful small annoyance of explaining your reasons for not making unfounded assumptions.
Hah. That was a lot of text, but it did include some advice on how to proceed instead.

In short: Think critically, don't make assumptions - try to reason out how likely it is that it is the tulpa, in cases where it isn't already clear. Not knowing is a perfectly reasonable option when the goal is accuracy.(edited)
If you are concerned that the tulpa will be annoyed that you missed something they said, you could always simply say that you thought it might have been them, but can't be sure enough and want to be sure you are actually speaking to them.
My only point in the end is that skepticism is fine, as long as it isn't a blanket assumption that no responses are them unless it is extremely clear. Assumptions are the problem - skepticism and doubt without assumptions are fine.
