Nonbinary and have some questions about bottom growth on T!

All the changes testosterone gives I would be happy with, but I’m not sure how I feel about bottom growth or what that would necessarily look like. The most recommended places to go see what bottom growth looks like (that I’ve seen) are r/growyourtdick and then porn subreddits. The vast majority of the bottom growth I’ve seen on them is pretty large, and I’m wondering if there’s a size bias when it comes to posting. I also noticed a lot of people mentioning pumping on there, and as someone who’d like to have minimal bottom growth that’s not something I’d do. I suppose my question is this, how much bottom growth is the norm/individual experience or how much of a range on it is there without pumping? I know genetics and pre existing size are involved so it varies per person, but still.
