While I think it's worth trying to be more open, at the end of the day the only thing you truly need to do is make sure you're comfortable. Don't force yourself to be more open or kinkier if it doesn't feel right for you. And of course if you ever need to talk, kinky or otherwise, bun has your back

Oh yeah, I wouldn't go further than I'm comfortable, I'm just realizing that the anxiety about it is in my head and that other folks enjoy it too ^ ^
