Ouch that's gotta hurt. But I'm curious to know why you'd think bottom surgery would make your dysphoria worse. Maybe the results aren't yet 100% sophisticated across the board--but people have had amazing results and there's at least one guy here who's had his post-op junk 'pass' to a medical professional. I used to be against the idea of myself getting bottom surg too, just parroting that crap idea that the results are poor and not worth it. But once I did my own research there's a lot of good to be found. I am now quite certain I want lower surgery. By the time I'm able to afford it I'm sure the technology and procedures will have gotten even more advanced. In any case I'd much rather have genitals that, while they may not look picture perfect, are more natural to my identity. As it stands now I can barely stomach seeing my lower half. The thought of one day not being repulsed with my genitals is quite freeing.
It does get a little nerve wracking when the subject of cock size comes up, though. One time I was sitting outside on my break and my boss came and sat next down to me. There wasn't a lot of room so he had to squeeze in and I jokingly flinched back and said "Whoa too close." He said "Wow tvc that's a solid 2-incher you got there." I said "It's three and a half," which, technically it is, because that's my packer size

And my boss shoots back "Some women like it that thick." LOL
Seriously though you just have to keep rolling with the punches, they give you ->-bleeped-<- and you just have to keep taking it and dishing it back... doesn't matter if they know your trans status. It's not really a matter of being immature (in any sort of malicious way, at least), it's just socializing/bonding.
