It started for me at about 6 months on HRT and has continued since for almost a year (I'm just about 18 months on HRT now

).
It just sort of started up all on its own (no one plays with my boobs as yet :p ), one day I took my bra off and noticed some sort of gross crusty stuff on the inside where my nipple would be in contact with it... So I looked at my boob worried I might have an infection or something, I couldn't see anything so I squished it a bit and some whiteish fluid came out.. I thought 'uh oh- infection' but it wasn't sore or inflamed, I tried with the other side, and the same thing happened, it kind of freaked me out a bit, but I was pretty sure it wasn't and infection at least

And it hasn't gone away, kind of a lot comes out if I 'milk myself' but I usually just leave things alone and it hasn't gone away

The one thing I have to say about it is that, although I still have really small boobs (like many out there) it helps me stick up for their real-ness/genuine-ness- they might be little but they work! :p
So I'm not sure if there is much rhyme or reason to it, the only thing my endo said about it was that it might the cyproterone, as its a progestin... Maybe it depends on how your body interacts with the cypro?
Does anyone here lactate but use spiro as their anti androgen instead? That would be interesting to know
