An ex girlfriend of mine used to put a polo mint up her flap, let it melt, then i'd dive in. Apart from being totally ludicrous, it actually tasted amazingly good.
Every girl should douche, but that's not really practical when you're trying to get the sawseech wet. It's much easier to pull out a wipe and swipe than pull out a douche and tell her to rinse that shit out. I wiped her balloon knot as well since I definitely took a trip down that path.
a sticky subject, no pun intended! (well, maybe a little one.......) after flunking the "sniff test" (front or back), rather than embarrassing the other person by mentioning the offensive odor i casually work a baby wipe into my technique.
