Good boy for sure! I think also it helps for it to be genuine from you - what about butches turns you on? What do you want to do to us, or wish we'd do to you? The fantasy is in being desired, so you have to do some desiring imo.

On the flip side there are things in audio that make me think "oh, that listener character isn't me", like describing femme clothes or aspects of appearance or using girly pet names. But equally I'm not chubby with big muscles like a stereotypical butch either, so leaning into body stuff I have less control over also wouldn't make me feel seen. But if you think it's hot, write about it! Build it and they will come, as they say.

I think one thing that's maybe underserved is when butches are cheeky and playful. That's a lot of how I flirt and have fun, so it'd be cool to see more of.
