I just don't feel lustful enough in this area of sexuality to say I could make it a significant part of my sexuality. An occasional unexpected visual stimulus, maybe, but very fleeting - curiosity perhaps. I think Hank just about summed it up for me - the intimacy, perhaps an increased closeness scenting all secretions from ones most loved partner, any waste product from sweat to scat to tears. Not an ingredient I would need to seek out, anyway.
All
to those who do, though.
