After all these years its hard to remember life before hand.
I'll break it down into points to make my reply easier
Clothes:
It means I can wear what I want, if I want jeans, a skirt, gym wear or even a bikini or shorts, I can wear anything without the worry of movement or sight down there.
Toilet:
I was never someone who "needed to sit" before hand, now its just nature for me.
Sexual arousal:
No real difference other than I don't get that growth feeling and hard.
I still get butterflies, I still get that nice feeling all over my body, I do have different levels of arousal, sometimes I need something inside (normally when I'm with a guy), other times I need to be just touched.
I would now say theres a difference before horny and turned on.
Horny is that feeling that you'll like sex, turned on its you need and want it now.
Horny, no real wetness, turned on, well its a broken tap

Sensitivity:
I have 2 places that if you touch you'll end up with a broken nose because I'll jump.
the first is my feet, they cannot be touched at all
the second is my clitoris if I'm not ready.
I jump, it feels nice, but too nice. After I'm warmed up it feels great
