Wah.... i think i got a lot of spare change. Here's some more of my $0.02 hor......
Turning On. Most guys are turned on by sexuality, most girls on the other hand are turned on by sensuality. And what do i mean by sensuality? Simply put, things that appeal to the five senses that will in turn cause the girl to "feel sexy" or "want to have sex". Examples....
(1) Smell. Different girls respond differently to scents. There are commercially marketed perfume/cologne that are guarunteed to increase you sexual attractiveness, but i think that's bullshit, coz as i said, diff girls respond diferently. Some may like it, some may hate it.
(2) Hear. Turn on some soft music. Sounds that would relax the mind and body. Basically it's background stuff that sets the mood and atmosphere. It was claimed by some sources that speaking dirty might turn on some girls. Apparently my girl don't really appreciate that, so i can't comment on this area.
(3) Taste. Hehe........ need i say anymore? Think, bro, think!
(4) Touch. Woo.... this one is the most commonly adopted approach. Stimulate her in her errogeneous spots lor. For details, refer to SGBoy2004..... but i suspect you got to pay school fees to get him to teach you.

(5) Sight. Certain actions definitely work out as a turn on. Moving your body (or certain parts of it) suggestly may be helpful, maybe not. Make eye contact that hold.... coz the eyes speak a thousand words. Mebbe even words that you never learned in school. Your mouth and lips too, simple things like pursing your lips or lightly licking your lips may convey all sorts of meanings when your girl see it.
