A Bunch Of Questions!

Hi AskTG! As the title suggests, I have a few questions for y'all. For context, I am a DIY MtF, 25 years old, employed, in South-East England, started hormones only a couple of weeks ago. Onwards!

Ein: In an effort to lose some extra weight and tone up a bit, I want to start cycling to work (some 4 miles, too far to walk). However, I do not own a bicycle. Obviously I need to get one, but as I am transitioning, I don't want to have to get a new bike after I go part/fulltime. My question is this: Do you know anyone who actually pays attention to whether someone has a man's bike or woman's bike? AFAIR there is a difference in the frame and I don't want to end up being mis-gendered due to something ridiculous like the shape of my bicycle.

Zwei: As I said, I have been on hormones for a measly two weeks. I'm looking forward to everything that'll be thrown at me in the weeks, months and years to come. However, even after such a short space of time, I've already noticed a couple of things, such as sensetive chest-bits and, surprisingly, already a decrease in my erection amount (down to one a day already!). Normal? Or is my brain helping me out a bit here?

Drei: Shaving tips. I know this is an issue for lots of people, and I've picke dup information here such as soak hair conditioner instead of using shaving cream/gel. However, I still get razor burn, and I think it might actually be the brand I'm using (Gillette Mach 3). I only get razor burn on the bottom of my chin, but in my haste I sometimes manage to cut my face, too. Not an issue for me now, but it will be in the future. I'll have to be more careful. Can anyone recommend me a better or different brand or model? I'm looking for specifics here, people!

Vier: I have run out of questions. I think those were the main three anyway, it's early, so I have an excuse. Wanna say thanks to everyone, too, without you I'd still be waiting on the godsdamn NHS. Still waiting, but at least I'm not idle.
