I’m much the same! I rock climb (like a lot) and it means I was strong even before starting HRT. The really nice thing with climbing though is that first of all, it’s queer as fuck, and secondly it’s super body positive. Like if you’re a femme with wide ass shoulders and a strong back that’s first and foremost seen through the lens of climbing, not traditional gender roles. This means people will sort of fawn over each other’s muscles no matter their identity or presentation. Besides everyone secretly (or maybe not so) wants a gal who can pick them up and toss them around!
And it has come up in very affirming ways! Like there was an impromptu arm wrestling contest at a lesbian bar and the strong femmes were right there with the muscled butches going at it, getting cheers, being hyped up. It was great!
So glad you’re finding the joy in your body what ever it looks like! You look wonderful!
