Analingus, not coprophagia
When I posed the question I'm was talking about the act of analingus: licking and kissing the anus, making love to it. I'm not talking about eating stuff.
Seems to me it is a deeply intimate act. Submission? Nah I don't think so, although it could be part of that routine. It could be used in a dirty, submissive sense.
But when its given and offered, purely to tantalize, tease, arouse and enflame one's erotic response I think it helps round out the entire act. Its obvious there are millions of sensitive nerve endings around the anus...the gentle action of a tongue on my anus drives me wild...so it must have an erotic function.
I was with one SP who went wild giving me analingus, and she explained that she never got a chance to do it with her boyfriend because he thought it was a 'gay' thing.
If you raise yourself up a little bit to give her better access then she can also fondle your balls and stroke your cock, then you have an incredible combination.
Taste? Well, cleanliness is important, as it is with blowjobs or DATY. With a clean anus the taste is probably more coupled to your imagination, enhanced with the natural taste of arousal. The warmth, moistness, depth, all combine to leave a taste of pure sex. That's the taste to me. Think oif how wine lovers decribe their taste experiences with wine!!
I always go into any date with a SP absolutely squeeky clean...anticipating the opportunity to receive rimming, and not wanting to diminish the possibility. Oftentimes I am not disappointed. Siometimes a SP will take more than 1 visit to get sufficiently comfortable to engage in it for you.
Seems many guys have a hangup on it, and may be missing out on a sensational erotic experience. In contrast to submission, maybe some guys feel it is opening them up to a vulnerability, surrendering themselves entirely to the girls attention.
So...that's my take on it, coming from a sensual romantic who wants to fully savour this rich experience.
