Hormones can greatly effect your "mindset" in regards to MTF as well as FTM. Im my case, i felt more feminine, more abstract in thought processes. Thinking more about what ppl have to say and in reasoning with ppl. This is not something that changed for me drastically, because i was always in a female mindset. I always had the opposite gender specific role of a female than a male, that is why i had such difficulty when i was an adolescent. I was never able to relate to men on a male/male relationship. Whether it be one on one or in groups, i was always an outcast. It wasnt even sexual feeling, but in how i thought. Later as i grew sexually, i was brought up by hetro parents, so naturally i tried, not knowing that i was even TG to have relationships with women, but when it came to intimacy i was always in the female mindset to even be able to perform. I didnt even really know i was doing this, but even with the girl not knowing and her being hetro, i was in my mind thinking more about me being satisfied as a woman would be. It is rather confusing now that i reflect on it. But to answer your question, yes hormones will help greatly in putting you in the "mindset" of the opposite sex, but as i have said b4, you can not change your character from one sex to the other if you are in fact not transgendered. Sooner or later it will catch up with you. Find out first if you truly are TG b4 and are ready b4 ever starting hormones, especially if you are a younger person and do not know for sure one way or the other.
