Before I acknowledged that I'm transgender (also around a year ago), I had a functionalist view of happiness. I felt happiness was maximizing my utility to others.
Even though a part of me has always known that I'm transgender, this view of happiness caused me to numb those feelings. Eventually, that path became untenable, and now, even though I sometimes question whether my current placation of these desires is worth the sacrifices, I know that happiness requires us to aim towards self-realization and have the self-esteem to accept being a disappointment.
I still can't unravel how feminine I would be if it weren't for the social constraints, and I don't know if I'll ever decide starting HRT and subsequently living as female is worth the cost, but as a result of modest placation of the desires that I can unravel and a resolution to continually move forward, my mind is calm, my outlook is optimistic, and my productivity is maximized.
You should resolutely experiment. I know I've peddled this advice to you before, but I think it's the only way to build the requisite strength to circumvent your fears, and accumulate the knowledge you need to move forward.
