I agree with you that sexuality can be fluid for some people. It isn't up to me to deny somebody's experience, if that's what it is for them.

"At least not for everyone" are the key words there.

It isn't fluid for me. It isn't a "choice" for me. It might be a choice for other people, and that's fine if it is.

We have to trust that each person knows themselves well enough so that if they are secure in their sexual identity, we believe them. Fair enough?
