Pre-T, I thought I was attracted to both female and males. But in actual fact, I was admiring their appearances, not actually falling for them or wanting to have sex with them. I was never interested in sex, never got that raging sexual desire towards another person. Sure, I have dated both women and men but in the end, I cannot fake something I cannot feel.
I did previously think of myself as a gay male and had sexual fantasies surrounding that identity, genuinely became aroused from it but I become equally aroused by the thought of making love to a woman as a man... then other days, I will have sexual fantasies of being a woman having sex with a man or a woman... what the...? Testosterone seems to take joy in making me confused!

Asexual before transitioning, still asexual during transitioning. Just more confused by the overwhelming fantasies that cannot translate over to real life.
