I had a memorable conversation about this topic with a Mistress I knew well a few years after I entered the scene. After a session I asked about the types of guys who are subs. Looking back I was trying to figure out how I fit in, or compared with, other subs. The Mistress made a telling remark, saying that some subs "dump" (her words) a lot of psychological baggage during sessions onto Dominas which was upsetting to her. She would then avoid those types of subs.

I remember two occasions where I had a first time session with a Mistress and could quickly tell in both cases that there was a problem - either emotional, chemical or a bit of both. I left as soon as I could. If either a Mistress or sub has a mental health issue, it is potentially a very dangerous situation.
