Asking for Kinky Favors from a Stranger

I would suggest dominant females, join some bdsm groups on social media to both get useful advice and this world is made for the kinky. Even so starting to foster a relationship based on consent is important and be sure to let any potential partner that you are into dominant women and are a bit kinky. Look for humiliation, Dom women sort of a thing. If you go down that road you should disclose that you are into x y and z and what you're looking for and also put boundaries in place. An experienced dominant woman will be able to guide you in the process.

The best thing to do is start a really trusting relationship and then proceed to get into a conversation about that. Asking might throw her off a bit but having a bond/trust with her can make asking really comfortable and you can ask her not to judge you or anything. I hope all is well!
