Hi, I am on therapy for 4 months, using transdermal bioidentical estradiol 1.5 - 2.0 mg, and spironolactone 50 mg to have a female body with good results, but there's something that bothers me. When I get aroused, my penis starts to grow and it hurts quite a bit. It's not a sharp pain, it's like I feel it growing beyond its limit, even though it's only halfway there. Besides the pain, it doesn't get as hard as it used to, which is to be expected. I also have difficulty reaching orgasm when masturbating, whether thinking about men or women (I like both). I know my erogenous zones are changing to a female pattern, but I'd like to preserve the male ones as well. I think bicalutamide doesn't destroy male functions because it at least preserves testosterone at its normal level. What do you think about this? How should I transition? What dosage of bicalutamide should I use?
