So I 20/f met a dom 37/m a day ago. We met on Fet and I mentioned that I wanted to learn more in general and that I wanted a mentor. He asked to take the convo off Fet and I agreed and we started messaging. He told me that my training would start today. He said that the best way to learn and grow is under a dynamic. I was not opposed, but I asked to get on the phone to speak more before starting anything official. He said that he wanted to continue over text so that there wasn't any misunderstandings. I asked what exactly would he be teaching me and I asked if we would be exclusive. He said that all doms train different and to remember that what I read online is not accurate and it is misleading. So everything I know can be wrong. He said that the vetting process can be applied through a relationship because it's easier to get to know each other. I gave push back on this saying that if we were going to be in a relationship then I want to get to know him outside of kink and vet him before getting into anything committed both inside of a dynamic or outside. I wanted to vet to sort out basic compatibility, etc. He responded that he followed the Old Guard ways or the true ways of BDSM. He said that if I wanted to do things the 50 shades way then we are not suitable because he takes the lifestyle seriously and didn't want to invest time with one who could "change her mind at anytime just because she felt uncomfortable about something". Sorry for the long post, I wanted to make sure that I got everything. So am I vetting wrong? I've never had any issues before now when it came to this. Is the old guard way like the proper way to vet?
