Heya Alyssa!
I'm so sorry that you had a rough upbringing, it seems all to common these days for trans and even non-trans folk!

I'm with you on the gay-bi thing, at least I think I am. Love is like special, but it also seems genetically male-at-birth puts love and sex in two separate categories. I've browsed my fair share, but never found overtly masculine features 'attractive' until I am in full-girl mode. Then, god damn, just pen me down and...what was I talking about?
That's awesome that your job is supportive, those are one of the biggest hurdles to overcome! I mean, we all gotta make money to live, right?
Since you were in the Navy and a marine, I wouldn't know, but that definitely takes strength and discipline, yeah? And not just the physical kind. And being MtF takes strength and discipline, so I feel like you'll do just fine! I can't believe you're starting HRT so soon, gosh I read so many stories of people starting HRT after years of changing their lifestyles- I really wanna rush into it, too, y'know?
Well, as you know, I've only entertained the thought for 1 month, but you've been training for this most of your life and more intensely in the past 2 years or so! So, I may not be able to offer advice, but keep me in the loop on how things are going and i'll do the same!

I have a twitter account, if you have one, too, lemme know!
Love all the support you've given to others, and I hope I can give you support, too!
