Puberty was terrible. I recall that when I first menstruated, my parents and I were staying at their friend's house that evening. The friends had a daughter who was a little older than me so we'd been pushed to be friends for years. And we were friends, it was just that we had very little in common, I would have preferred hanging out with her older brother but he was not interested.
Anyway, I think I was 13, or 12 going on 13, that night. We were getting ready to shower before bed and I realized I'd started my first period so she ran to get my mom. I was feeling a lot of dread, but of course I knew what it was, I'd just hoped it would magically never happen. Later, after I showered I came out and all the adults were grinning at me and congratulated me. I felt so angry and humiliated that they'd been told. Later, when we got home, my mom made me some special treat to 'celebrate' my 'becoming a woman' and I was so angry and sick to my stomach; I tried to be polite and I think I had a tiny bit of it but I mostly wanted to just throw up.
Worse was when my breasts developed, because up til this point they were barely an A-cup, something I could ignore while I played sports or ran around dressed like a tomboy, as the grown-ups put it. My chest was the worst betrayal because in less than 2 years they went from A's to DDDD's. Impossible to hide, hampering all my efforts in sports, and suddenly the focus of spiteful jealous girls and leering boys. I was told I was fat (because if you wear baggy clothes with a big chest, you look dumpy and fat regardless of your figure) or a slut. I hated them, and I still hate them, and the day I get them removed and thrown away like the garbage they are, it will be glorious.
These were the notable changes, which suddenly had people treating me like I was an incapable, stupid slut. If I tried to conceal my body I was mocked for being a fat slob, if I showed it off I was an attention-seeking whore. I didn't know what to do. I kind of switched between acting as both, I suffered from bulemia from age 16 until about age 23. I wore very revealing clothing and vamped at men because I guess I was playing into what was expected of me, and at the same time I was fighting hard against being the least bit masculine. All of this meant that men only saw me as a body and women thought I was a slutty bitch (these are not conjecture, and I'm not branding myself in this post; these were things that were told to me, to my face, or were said behind my back but I learned of it later). I eventually dealt with this by letting myself gain 150 lbs, although it was a semi-conscious decision.
I did learn that if you develop a busty hourglass figure, no one will have even the tiniest lick of sympathy for what you consider to be a curse. And I can understand that, it's like a model sighing about being "too beautiful" and how it makes life hard. Except, for me, it was like a cosmic joke--being saddled with an ultra-feminine body when my mind was wired to be male.
