I'm using PM and a couple of AAs at present and getting good breast growth. To keep my male sexual function for now, I take a 7 day break every month. In between, I have no interest in sex the way I did as a male. Late in my break that desire and function returns, although not as strong as before PM. I'm sure these breaks compromise my breast growth, but not much. I can't imagine making a serious go at growing breasts and remaining completely male downstairs. This is one area where it's hard to "eat your cake and have it, too".
