Open to exploring becoming a hotwife but so many questions

My husband and I have been discussing the idea of me becoming a hotwife. We want to take it really slow to start with and just explore posting and maybe talking to people first but I was hoping to get advice from you all on a few things: How did you first go about meeting a bull/where did you talk to them, Reddit or some other platform? Did you meet up casually before meeting them for the actual hotwife experience? How did you resolve safety concerns like privacy and STDs etc? Any other things to consider/things you wished you'd known before your first experience?

Thanks all, I'm pretty excited but have so many questions and don't want to rush into anything!
