I couldn't really tell you about the first time I inhaled the aroma of female including the genitals because basically my second head had taken over and "aroma" was not part of what I was thinking. If I was thinking at all.
Really it hasn't been until the last few years that I've began to really savor (?) what was going on and paying attention to what gets me there so that I can get there. With age comes appreciation for the finer points in life, I guess.
From what I understand, a lot of the smells or aromas or whatever you call them, are beyond the threshold of what a human can smell. As a guy, my age, it has to be pretty strong before it registers that there is something around giving off a smell or scent. At least consciously that is. Something about pheromones or "subliminal advertising" which I don't fully understand but don't discount it either.
Lora doesn't wear any perfume and never has, but sometimes she does smell like flowers just because she works with them. Sometimes she smells like something she had baked. If we are around each other, like just in a store or something, I know for sure that any cues my brain picks up are visual. If we are closer together, say within arms distance, then something else kicks in and I seem to be picking up on something else. Visual cues for sure, like the pupils of her eyes dilating a little when we look at each other and make eye contact. We make a lot of eye contact, speaking or not.
If we are in a store or out in public and she gives me a hug, then I feel her warmth and herself and I notice even more about her, like the scent of flowers or the scent of flour. 😉
If we are someplace where we can hold that hug a little longer or a lot longer, then I feel her body warmth and around the back of her neck, or side, just under her hair, I can feel that her warmth is more moist and warmer. I am guessing, but I think that something like pheromones are being given off and I somehow pick that up, even though I don't think my sense of smell or my mind gets it. The longer we hold each other the more we respond even if we aren't, at that point, caressing or fondling each other.
Once we start really touching each other and as we build those feelings, I know that her body heat goes up at the back of her neck. To be honest, I don't know if the pheromones she gives off, if she gives off any, have anything to do with "setting the mood", or the closeness, or just what it is. Whatever it is, and whether it leads to something or not, I like the smell of her and I really can't describe what it is about her smell or scent, that is just good for me.
I just don't know for sure and maybe it is just proximity but something works and it is always positive, regardless of end result.
