I was making out with this chick the other night, and she got so wet I could literally smell her pvssy as I was sitting on the couch next to her. We ended up stopping before any clothes came off, although I rubbed her enough through her pants to feel that she was completely soaked. My hand smelled like pvssy all night just from touching her outside her clothes - and btw this was a good kind of pvssy smell, not some rotting tuna stankness.
If you take your time and turn her on enough, it will be very obvious what she likes, because she'll moan and groan when you finally get to her good parts. I got that girl so wet without even touching her down there, by taking my time and teasing her. If you want to stimulate an area of a woman's body, in this case her pvssy, go everywhere but there and tease her around that area until she is begging you to touch her there. Anticipation is everything; it is very powerful. Most guys are in a giant rush - honkhonk, diddle diddle, "ok, let's fvck." Don't be that guy. Make her beg you to do more, and she won't be stopping you from going farther with her.
Oh yeah, and I second the 'trim your nails' advice. Wash you hands if they are dirty as well. If you cut her with sharp nails, or give her an infection with dirty hands, that area will be off-limits, so this is all in your best interest as well.
