I already talked about having that sensation earlier in this thread re: peculiar and new sensations in the perineum whilst aroused. Doesn't happen as intensely as it did the first few times but it still does happen. You can call it whatever you want, I was never too concerned about having labels for things, I just filed it into the number of new things I've felt on HRT, emotionally and physically.
Since I've been on HRT for more than 2 years, a lot of this stuff isn't as wonderous and fascinating as it was before. I'm simply growing accustomed to it. There are times when I even forget to take my dose for several days, but eventually the mood swings and dysphoria swing in so hard that I can't go without for long.
I will say however that my interest in pursuing SRS has gone up exponentially. My genitals remain the only physical source of dysphoria left on my body and it feels like a cramp on my ability to pursue intimacy. The next time I talk to my endocrinologist I'll be inquiring about the steps I can take to get there, and I also plan on getting my name legally corrected before the year's out.
As a side note, after living in female dorms for the past 3 months I've just been using women's restrooms out of habit in public and things have gone well. When I have to get a key it's like a 50/50 toss-up whether the gas station attendant gives me the right one, but none of them second guess me when I politely correct them.
I still get misgendered occasionally but I tend to let it fly unless a person does it more than once, then I correct them by saying something like "Erm, I'm actually a she."
