Thanks for posting this. It was very interesting. I consider myself primarily a masochist and only secondarily a submissive. The impression I get is this young lady was the same way. And while she talks about endorphins the punishment vibe is important to her as it is to me. What disappointed me though is her highly speculative self analysis about a childhood trauma. Ah the kinksters are all damaged goods trope. Sigh. A more likely explanation is she goes through phases which would be similar to my own experience.
