I had this thought: Not to give time to enjoying your bodily sensations is wrong, is unchastity. We have to take time out to play the erotic zones of our body. The practice is needed for both psychological and spiritual health. Down the centuries a lot of ideas contrary to this have been hammered into people as forms of asceticism. This has been very harmful. If we ignore our body, our erotic self, we ignore, deny about fifty per cent of ourselves. We finish up distorted or half alive personalities. This is against truth and, therefore, against chastity.
Then I thought, well, what do I mean by our erotic zones. I know that I get sensations of pleasure and electric energy that go through my body when I finger my tits, caress my balls, stroke my cock, palm the inside of my thighs, but perhaps other people can get the magic working through playing other zones. So I googled "male erotic zones". Largely I discovered from something from the Times of India that it could be almost anywhere, if the touch, the caress was sufficiently delicate. A reference to the scalp as an erotic zone recalled to my mind the time I got tremendous pleasure and comfort from a guy wearing combat pants who gently fingered my scalp for about an hour while I sucked on his cock. A very satisfying experience.
