Your clarification helps a lot.
You are right: hormones do not make the man. They just sometimes make the man feel better. There is no such thing as a "profile of the FTM" even though it may seem that way sometimes.
I think it sounds like you need to get off the birth control pills, asap. Those hormones (estrogen & progesterone) do affect different people in different ways, and it sounds like it is not working for you. (not uncommon at all)
As for certainty - I think we are all different in how we view certainty and risks and making decisions. I am absolutely certain about taking T for myself, but that doesn't mean I don't have ANY concerns about the effects whether short or long term. People who are willing to take HRT with permanent results either have some concerns that are clearly outweighed by the benefits or if they have 0 concerns, it is that they are overwhelmed by dysphoria or circumstance that they are unable to process/consider the negative effects, which is produced from the sheer intensity of the difficulty in living without the hormones.
I am simply certain that *right now* I am willing to take on the risks of negative consequences as a trade-off for experiencing the good consequences, and that if that calculus changes, I can change my mind and stop taking T. I also am ok knowing that if I ever stop taking T or wish I hadn't, it will be costly, challenging or on a rare occasion impossible, to 'change back' to how I was before. Any good health care practitioner will understand that this is within the range of healthy adult decision-making and behavior.
I'm not sure how you mean "try" & I think that's the area where you seem frustrated. Maybe it is just semantics and communication. Have you ever heard the expression there is no try, only do or do not? A lot of people are reacting to your comments about wanting to "try" and seeing it as being less than sure. In reality, you can either take or not take hormones. You can't "try" to take hormones. You will never be 100% certain that T is right for you without experiencing it, but you should be pretty darn sure that you think it WILL be right for you before you start, because there is no such thing as trying it out, to the extent the effects are permanent and sometimes fairly immediate. Maybe it would help to ask yourself: how sure am I on a scale of 1 to 10? why am I not sure? what would have to change for me to be less sure? to be more sure? That might help you figure out what it means to be certain it is the right step for you to take right
now.Here is another way of making that less abstract:
To use kyril's awesome expression, I have no desire to be a bald potbellied pizza-face with a patchy beard and back hair. However, if my choice is to be that or to be the most beautiful woman in the universe, I'd still rather be that dude. I could exercise and work out. I could shave my face and wax my back. I could see a dermatologist for acne treatment. And I could learn to like bald or deal with it in other ways (hats, caps, rogaine, whatever). But I would still be a dude and I'd still have the *right* chemicals in me for my brain. The question is: are you ok if that happens to you and would you view that as being better than being a cute little genderqueer/girly-seeming person? if the answer is yes, then maybe you should proceed to T. If the answer is no, then you may not be ready.
