Yeah, 3+ inch girth is usually the limit I've seen for most other docs and characters. Even so, that's a THICC dong for a virgin to take.
So yeah, it likely would be around that, maybe slightly less if changed... I don't think I'd make it less than 2 1/2 though or more than 3 inches. (Cuz I can't even come close to wrapping my hands around something more than 2 inches wide haha! 2 1/2 is like stuffing a soda can up your vagoo/ass! Then again maybe I'm thinking too much on RL applications
) I haven't gotten votes on that yet, but that's kinda what I'd feel comfortable setting her limit to. That's mostly something I was gonna think about after I get her sex scenes down and finished.
