Not sure if I count as a regular poster, but what the heck :)
I actually haven't done much... yet. I've kind of always been obsessed with the idea of being feminine, but only recently started to take action on it. At first it was just because as a guy, I was always told I had a decent ass, so I tried wearing women's leggings to see if they were different to compression tights that guys sometimes wear to the gym. And I was quite surprised to see that my ass looked significantly larger and better in women's leggings. Maybe it's something different on how it holds the shape up and rounds it off.
Then I ordered some g string panties online and tried wearing them under the leggings, pulling the string up and above my hips so that you could tell how slutty it looked.
Since then, I've experimented with things here and there. Being able to see the bulge of a chastity cage under skin tight leggings is hot, and I've even managed to stain the front of the leggings a few times because I just dripped so much. I've tried playing with my ass a few times, but haven't been able to have the best experience yet.
I've always imagined/dreamt of having massive tits, and I've tried a few breastplates, but haven't been able to find any that are a right fit for me yet.
Guess I'm only just getting started! :)
