There's various things which weren't "strange" per se to get used to, but rather a shock, because even if you can intellectually accept that they happen - emotionally, you aren't ready for them. Street harassment was one of those stances, it started happening very fast and I didn't have the knowledge to defend myself. I also must say that I have worked door-to-door in quite rough conditions and undefined terms when I was 18, so that made me even more vulnerable to street harassment. Many men would invite me to get in their apartment and some would even be quite furtive in their approach. I found myself in some quite stressful situations. One time, as I was leaving a building I had "pitched", I heard a stream of catcalls. I looked back, a group of 10 guys were looking at me and asking me to get closer, give them my number, etc etc. It was scary and I ran away. I have countless of these stories. The environments I was in and the fact that I worked until late in every job I had didn't help prevent this from happening.
Another thing is that you will have to get used to people commenting how you look, to your face or behind your back. Whether it's good or bad. If you are pretty or are not, if you look good in that dress or not. Scrutinizing is a thing. Especially in the workplace. Watch out for shorts, leggings, dresses, showing too much leg...etc. You will get looks, mostly by women. Many of those looks will be nasty. Sarcastic remarks are also quite common, especially if you make an effort to look good on a particular day. Also, men intruding your personal space IS a thing... one of my managers at the call center must have found me endearing as he kept touching my hair as I talked, until I respectfully told him to stop. Another time I was in a coffee shop, late at night, I had just had dinner and was making time to meet a friend when a middle-aged man came. He started talking to me asking for a charger for his phone, he kept asking questions and trying to make conversation and then talking about his love life, soon enough he was sitting beside and rubbing my thigh!!! It was scary. I demanded him stop, took my charger and thank the heavens, my friend appeared! We fled from that place.
As for the positive, I can talk to other women and actually feel a connection now. I have started conversations in public transportations a lot, and other women have started conversations with me. They just happen in the most random places. And it's good to be able to connect and have a true girl-girl friendship and enjoy it. We aren't a threat to each other and that it's so comforting. There's mutual understanding. Some of the best conversations I have had in my life were with female strangers in public transports at night. Funny thing!
This is just some things I can think of. There's probably more. Overall, I can say transition was very rewarding and to be able to live my life as a young woman is something I'm eternally grateful for. SRS and BA were the finishing line of this journey and I can't imagine myself without these. However, there are drawbacks and women still get very much second-class citizen card in many instances, even in the West. But it's still much better than in the rest of the world.
