How?

I’m eighteen and pretty large, and I’ve been wanting to slim down so that I can look a bit more feminine. When I was younger, like 13 to 15, I was pretty slim and I had a very feminine face (if it helps to visualize, my family always used to say that I was so pretty I should have been born a girl). But then I stopped working out as much, with Covid and all. And I’d kinda like to get back to having a more slim profile, so I’m kinda wondering if it’s even possible. I have a bit of a belly, but nothing too crazy, and I don’t think I would have any loose skin to worry about, and most of my fat is in my thighs and butt. I don’t think I’ll ever be dressing up like a girl, but it would be nice to feel a little more comfortable with my body. And less important,is it possible to get a more feminine butt without getting on hormones or anything?Because a lot of the femboys I see that have really good butts tend to also be on hormones.
