This is a Tough hot-button topic. I’m impressed with the considered discussion here. I was a competitive swimmer my entire life and know well the advantage I had as a male vs the average woman. To be sure, there are exceptions, but even post op, post transition I’m still a head taller than most women. No one knows I’m Trans in the pool but I often get comments about how fast I am. For me, my transition is more important than winning any competition. I would rather enjoy the success of just being myself.
