I'd still transition. My testicals are like so small now its just like well good luck with making me 'ejaculate'(possibly TMI lol), but heres something interesting and Im not sure if this is just me or what. Ok say something is going on sexually, when Im aroused I basically leak fluid, same as before(males do this just prior to sex ie. natures lube) except now it happens alot, throughout the process, pretty much constantly. I cannot ejaculate anymore, wont happen, it would fall off or cause me so much extreme discomfort from endless friction that its just a waste of time, but interestingly my brain still goes through the motions of an 'orgasm'.
Like I said this could just be me, or it could be quite common with Tgirls, not entirely sure. And tbh, I prefer this way of orgasm, it lasts forever, can happen multiple times, and less mess....yay!
