Hi Latrell, I can pitch in for the next decade or so, early 80s into mid 90s.
1) What is your gender? (exactly what you call yourself)
Female. XY chromosomes.
2) What pronouns/name do you go by?
I/me/my.

In the third person I've always been he/him/his. I've not transitioned and am out only on a limited basis. People see what they expect.
3) What sport did you (attempt to) participate in?
Football or, as the Americans call it, soccer. Swimming. Fencing. Mountaineering. Karate.
4) Does this sport have a separate female/male team for you to participate in?
Yes for first two. The rest were co-ed.
5) Which team did you go on and why?
6) Which locker room/bathrooms do you use and why?
The male ones. My experience was the same as Sam's; it wasn't even a question so it couldn't be a choice. At the fencing studio there was only one bathroom so it was unisex.
7) How were coaches towards you? How did they handle things?
Oblivious as best I can recall, though that's unsurprising as this was a time in my life where I was very deeply stealth.
If you were like me and were put on the team with your biological gender, like for me it was girls track, and wanted to be on the team for the opposite sex, can you answer these questions:
8 ) Why were you on that team?
Football was a neighborhood thing where a bunch of parents got together and made up a team from their kids. I'm not sure how I ended up on it, actually, but I didn't mind it. Swim team was when I was bit older and practice was at a predominantly adult facility where I felt safer than I ever did at school. Plus it got me out of taking physical education at school, meaning I didn't have change in the locker rooms there. That was quite a relief.
I started fencing because a male cis friend invited me. Stayed because I could hang with a number of cis female friends and the older guys there didn't care who or what you were so long as you were serious about weapons training. The studio's fencing master was super nice and I really really liked my sabre instructor. Older guy with the long hair I wanted who took me under his wing, gave me lessons, and let me borrow bits of equipment I couldn't afford. Better than my real father, but that's another story.
Mountaineering was a similar escape. I liked the land very much but the group was quite male. Didn't enjoy that much, though I found some refuge by hanging with the responsible adults and the one cis girl who came.
Karate was for self defense. I was also trying really hard for a while to have a hetero crush on the sensei but wasn't able to pull it off (I'm lesbian but have always kind of felt like I should like guys).
9) Why couldn't you be on the other team?
10) Are you comfortable with the team?
11) Are your teammates comfortable?
12) Are you more comfortable with the other team? Are they more comfortable with you?
Given being on the team of felt gender wasn't an option these don't really apply. Swimming and fencing were the best as the groups had even numbers of both sexes to a slight majority of females. So I had other girls to be around, if only implicitly.
13) Where you made fun of, bullied, verbally/emotionally/physically hurt, or threatened?
14) How did coaches handle this?
15) How were coaches towards you?
Yes, yes, yes/yes/yes, and yes. However none of it happened in a sporting context so the coaches weren't involved. I did quit karate as the sensei's behaviour became a bit cruel and I'd become physically afraid of him. The fear was my hangups from childhood abuse and his cutting remarks didn't have anything to do with my being trans.
