First of all I'd like to thank you for even thinking about doing this. Most would just go off of stereotypes, and not do this. Props to you!
1. I knew I was trans when I told someone and they started calling me by 'he' pronouns. It felt amazing, and so much better in every way than being called 'she'
2. My girlfriend at the time threw her hands in the air and screamed with glee "I'M STRAIGHT NOW YESS" It was hilarious and still makes me smile to this day
3. From my mom. I didn't get to tell her myself and she walked in while I was trying out different binding techniques. She didn't yell, but I could feel the disappointment radiating off of her. She still doesn't use the right name/pronouns even 3 years later
4. That I am not open about questions like this. I for one and totally fine with answering questions about being Trans. I would rather be put on the spot and listened to that let that person stay uneducated in this topic. The more people who understand even a little, the better.
5. I like that if I tell someone, they seem to be more trusting to me. I told them one of my deepest secrets, so they usually are more trusting to me, which I think is cool. Also, I get to see people in a different light. I can be pissed at someone, and they pissed at me, but if they still use the correct pronouns and names, or at least correct themselves if they mess up, it makes me feel awesome. Because here we are, furious at one another, but they still have enough respect for me to do that. And that makes me so happy.
6. At school, I use the mens bathroom, and in 9th grade I didn't tell all my teachers about it, so the next year in 10th, I came face to face with one of my teachers I didn't tell the previous year while I was going into the bathroom, and him leaving. He seemed so confused and concerned, but luckily didn't say anything. I try to avoid that teacher now...
7. Bathrooms. Periods. Binding.
Bathrooms are trouble for all trans people, becasue they don't know if they 'pass' as their gender, or if they'll meet someone in there they knew pre-transition and how they will react. Also the possibility of being called out, harassed, or even beaten... It can be scary just to go into a bathroom you feel more comfortable in...
As a FTM, pre-t I still have periods and they are just ugh. I can't explain why I'm in so much pain to people I'm not out to yet, buying pads is embarrassing when shopping with parents and just... I don't want this thing in general, and I REALLY don't want to bleed. *also my mom usually used my period as a reason to down grade me and my male-ness*
Binding my breasts... Ah the back pain, discomfort and fear people will see my binder is really bad, but I'd rather have that then wear a bra, or have them bouncing around in public. Ugh...
8. Honestly, I'd like to change education on it. The more people who know about it the better. That way, people will see on their side, and try to make other adjustments to treatment of them. Possibly having one gender neutral stall per 10 gendered, would be a thing I'd enjoy, but other things would come out of education.
9. Most of the time, it's not my body that annoys me, especially because I have so many supportive people, but what usually makes me feel dysphoric (Dysphoria for trans people is kinda like depression centered around one's gender. Where you feel bad about stuff, there is body and gender dysphoria, which are similar but different.) I usually don't feel body dysphoria, unless i'm on my period, but i feel more gender dysphoria. This is when I hate myself for not being 'male' or that i'm not acting masculine enough. Usually this occurs when people say 'she' and doesn't correct themselves.
10. Sometimes I really like gendered products, like I feel empowered and happy that I have 'male' deodorant and razors, but it makes me feel a bit guilty when I use a traditionally feminine product. I'd rather have products, especially grooming products to not have genders, so even cis males could use teen spirit's Pink Crush and not feel bad. If you wanna smell like what ever phoenix or lavender honey, you should be able to without fear.
And I don't see any of these that are offensive.
