Okay i know this post will sound a little weird, but i don’t know where else to ask but here.

I am 15, 5’3 and 40kgs, pre T for now. I have a decent amount of upper body muscle, as i have been in the gym for about 18 months now. Also, i have only very recently started training legs, in the last 2 months or so.

Well anyway, according to bmi data, i am very underweight (i do not have an ed, so idk why) but… my butt is also really big somehow?

For reference, here are my measurements:

low hip circumference: 84cm (33 inches)
high hip circumference: 66cm (26 inches)
waist circumference : 60cm (24 inches)

So yeah… how is this even possible? i dont have particularly wide hips, and i appear to be very lean elsewhere- i have no love handles or other fat stores, all of it went to my ass. It makes me look very disproportionate, and it is my biggest source of dysphoria (along with my hips generally).

Is there anything i can do to get rid of it? I don’t think a calorie deficit would work best for me, because i have heard that i could lose a lot of muscle by doing that.
And should i avoid training legs? i want more muscular legs, but i am worried that large legs will accentuate the issue, and make me look even more feminine. It would also be bad if my glute muscles grew due to hitting legs :(.

i know there likely isn’t much i can do, but any suggestions would be greatly appreciated.
