I'd probably get the shit beat out of me for acting weird.
I'd freak out for sure. I'd be so tiny for a guy it would suck. My dad is tiny.
I might lift heavy stuff just because I could. But I wouldn't be able to see what it felt like to have sex as a guy unless my husband also transformed. And even then, our orientation wouldn't necessarily change, so we probably wouldn't even be attracted to each other.
It sounds like a bad dream, tbh.
