You're welcome! Actually, I'll add that (and this is very hear-say without strong data), many dominant types I've read about or chatted with over the years have reported being less able to tolerate it, rather than more able. It strikes me as a much better at giving than receiving kind of thing. Though, I wouldn't get hung up on that or have strong expectations there. Even if that stereotype is somewhat accurate, variations are bound (heh) to be encountered. So, yes, lean in to the uniqueness of that person and just enjoy their authentic reactions.
If it's a paid session, or you expect some non-trivial expense involved, I'd first get some good feedback from them about how ticklish they are. While I don't usually encourage transactional sessions as the best session approach, if you do, you'll want to have some kind of idea of what you're getting for the payment, unless money is of no worry to you.
In either case, another consideration is going over with them (because they are unfamiliar with this world) what both you and they expect. It could be that they don't know how ticklish they are and if you go in full blast, you could run the risk of losing out on potential future experiences with them. If you plan on doing recurring sessions with them , Make it fun and go slow and easy, getting feedback from them as you go. You can discuss increased intensity for future sessions afterward and see how they feel.
Good luck! 🙂
