Those who were lesbians before, did your attraction changed after going on T?

I am not on T yet and I’ve never been attracted to guys. I also have a girlfriend that I deeply love. She accepts me for being trans or at least non binary for now. I heard that some who went on T started being attracted to guys either more (being bi at first) or those who have been into only guys intensified their feelings. Is that true? What is your experience?
