Okay, let me set the stage. I NEVER had any satisfying sex for most of my life, EVER. From the moment puberty started and I was jacking it for the first few times, to the literal moment I had left my ex (which we obviously fucked a few times), I had never had sex that I liked. The reason I appreciate these "sexual things" so much, is because I never had them, and honestly, I should've been. Sex is literally in the top parts of Mazlow's Hierarchy of needs, which means that I SHOULD'VE been having satisfying and fulfilling sex for years, and yet I wasn't getting it.
Also, I'd like to say that it's perfectly natural for me to flaunt boobs and stuff that I never got to have growing up, and it's perfectly normal to want to be proud of my new body and what it can do, regardless of whether it's lewd or not.
Think of it this way:
Imagine that you're an avid gamer in the 8th generation of gaming, but you're stuck with only an N64 and a CRT display. Of course, you're jealous of all the people that have the new Xbox One: which can run games in HD, and has a lot more processing power to run better games, and has multiplayer for most of its game library. Naturally, you end up getting jealous, and feeling left out that you don't have the latest console, and that you aren't able to ever play it. You go years running on an overpowered console and feeling shitty about yourself... until suddenly, a relative you haven't heard from in over a decade randomly comes in and hands you a 4k TV and an Xbox One. You actually become proud of your new found console which is way more powerful and more efficient hardware wise; you start to take screenshots and flaunt to everybody how you can now play online and in 1080p, because your previous device was so goddamn underpowered that it could rarely handle more than a dozen polygons.
It's literally the same thing with me, just take the console allegory and replace the underpowered hardware with inadequacy comapred to cis women, and replace the N64 with my pre-transition body, and the Xbox One with my post transition body. Like every other human on the planet, I feel happy about a clear step in the right direction, and naturally, I tend to flaunt it.
I don't show off my boobs because I have a sick fetish and I get off to showing my boobs, I show my boobs because I'm finally happy that I can feel comfortable in my own skin, and to me, that's an accomplishment worth proudly proclaiming. And as far as the sexual encounters, can't you just let me have my cookie? If I've had trouble actually feeling satisfied in bed for most of my life, I've found a partner that can make me happy in bed, and transition can help me feel more comfortable in that situation... who are you to put me down? Yes, I talk about sexual things occasionally, but if you took a second to look at my post history on ALL trans subs, you'd see that the nsfw only makes up a small percentage of what I normally post, most of my other posts have very little, if no NSFW mentions. I more often talk about how I'm sad that I don't pass, and how I'm so depressed I don't care sometimes than "MY GIRLFRIEND SLOBBERED MY LADY COCK ;lsj'kgsaj'dsakdsaijfd;"
I'm not saying anyone's perfect, but it seems like this whole post portrayed more of my bad moments than my good ones, and really, it's a very thin line between laughing at someone on internet forms and launching a smear campaign against them...
