Post-Clarity Melancholy and the Male Orgasm

I’ve read about the chemistry associated with male orgasm. I’m interested in the effect of prolactin. Prior to chastity, I was not aware of the impact of prolactin. I am now. After a couple of weeks being locked up, the impact of an orgasm can be quite detrimental to my mood. I am learning to watch for it, and to be careful in my interactions with others. The impact to me can last for up to week. Is this because:

1. Before chastity, and having orgasms frequently, does the brain become desensitized due to a constant bath of prolactin? As a result, you didn’t notice a change in mood after an orgasm?
2. With chastity, and fewer orgasms and less prolactin, is the brain now much more sensitive to prolactin, and the impact is much more noticeable?
3. Or, the orgasm felt so damned good that I am just really grumpy when it is over and it will be a long time before the next? Thoughts?
