Something that I realized only very recently. I haven't thought much about "scent," as long as there weren't any that is unpleasant. But I've learned and experienced that individual gals, especially after sex, can leave quite strong and unique scent. (Not perfumes or anything artificial)
Don't know if this is part of the whole pheromone thing, but when I come back to my apt after a session and lay down on my own bed to sleep at night, I can still very much remember and "feel" the scent. It's quite weird (for lack of better word choice), because that same scent gives me kind of comfort and relaxation (like cuddling or feeling of being a protected child) psychologically. When I see a particular provider for the next time, without me being conscious, that scent I think is the first thing that I notice. Very "erotic" and relaxing feeling that lasts for hours later, and is ultimately what makes me crave, even before getting horny sometimes.
I noticed that this one specific lady I've seen couple of times has the most lasting scent. Not sure if I could describe it as "stronger" scent, but I don't know, it always makes the lasting impression and feeling that she's still on my bed next to me. Actually, her scent is probably the only scent I have noticed as scent. I don't remember ever thinking about anyone's particular scent besides hers. She finds it weird that I constantly smell her skin out during the session, but maybe she figured it out. I can't say for 100%, but I feel like a session after DATY or any playing very close to V often makes stronger lasting impression. (It's weird thing to say I know...)
With that being said, I couldn't really find much discussions about scent specifically. I know it was talked about here and there, but the topic still remains mysterious to me.
