Longest I've used any sort of hormones?
about 6 months.
Longest I've stayed away?
Years.
Not by choice, which I think is the intent of your question.
But if we all had that sort of control, wouldn't we do it up right, right away? :-)
How may times have you been on and off nbe/synths ?
Synthetics: 2 times, once for 6 months, once for about a month.
NBE: Don't actually know; 5 times, maybe, for a month to three months? Then "real life" gets in the way again, and I have to stop everything I'm doing for ME, and deal with some other crises...
I need to grow a lot internally, I think. It's not the breasts, it's the connection, the social bonding, I've missed out on, and I'm seeing the "future" as a woman, where I'd be social, outgoing, and make friends... And the time is rapidly disappearing, and I've got a 52-year-old baby to deal with (I'm being overly harsh, she's clinically depressed and likely has some PTSD, but so do I, and I thought one of the purposes of a relationship was to salve each other's wounds - not to inflict one's wounds on someone else, and then belittle and berate them for not wanting those injuries.)
