When near more attractive women, I tense up ever so slightly, but also let it relax back out a bit.
I actually don't do it as obvious as that makes it sound, I am way way way more ninja, and almost entirely cut off from the girl (leaves just a trace, like a drop of blood in the water, rather than chumming the ocean). That sets a more realistic kind of "doubt" in her mind that stops her from doing anything too early.
Often girls are on the verge of dismissing what they feel about me, which is what I want because when girls are certain, they are all "hey there is that guy from before!" (They nudge their friends) that isn't what I want, I want her to subtlely adjust silently between her friends (that ludicrous nature is a protection mechanism).
Women are far more enticed when they don't have a garuntee (which really bluntens their emotional response range). And I prefer to be silent up until the moment I do something.
Its far crisper of a seduction that way, and helps bring out the "starch" of my masculine form (which sends girls into druel mode).
Think of it like, your normal mingle is a blueberry (they can take it or leave it depending on mood), but when you add control and "starch" its like a pie, and it makes them salivate and squeeze their toes a little, and because of that, they will wait all night for you if they have to.
They wait for me to end their suffering.
But I'm never that merciful
I'm ruthless with a bit of love leaking through from how emmaculately I do what I do :P
So yes, I'm a bit mellow, but its got this straight razor feel. It heightens the tactile nature of her senses, and allows her to be alert when we talk.
I am extremely conservative when I am serious about a girl almost to the point they don't know if I know anything at all.
That way when she goes out to the balcony and I slowly wrap my arms around her she just gently smiles and goes with the moment, gently letting out her sigh, because she already knew, and I'm letting her slip into that fantasy world, and away from her doubt.
And I very softly watch over her.
I try to seduce as subtle and as distilled as possible, because its much easier for me to savor everything.
If I just go wild I forget the feeling as soon as the girl is gone. And that sucks.
I only want girls that I like to remember and seductions that help it stay with me.
Thats why I'm more straight razor.
