i was worried the same as you but i found that instead of finding men attractive, now i just find them useful, lol i mean like a sexual interaction is a possibility, and i know there are still other ways to do it pre op but im sorry, im a lady that doesn't like it "that" way and it is degrading in my opinion, and trust me i have had plenty offers,
secondly your attraction to women will change, you will stop finding them attractive as a sexual object and start finding them attractive as a soul, for me it felt like before i was just lusting and now i am actually emotionally developed enough to love them, the way they look at me, the way they gently caress my skin, the way they sound when they are getting turned on.... one sec i am a little warm now, just deep breaths lol, my damn mind has so much control of my libido
