How do I tell this girl she has a stanky/sour tasting *****?

[Cherry Picker]

And what can she do to fix it to make it smell good and yummier?

Obviously you are dating a skank. Look for a nice girl instead.

If you really have a decent relationship with this girl you can clean it up.

Decent scented baths etc, check her diet..I don't know I never had this problem of being attached to a girl with a stinky *****.

Bubblebath?

tell her it stinks....

its a bit of both diet and hygiene

[omarinbox]

You ever used those fizzy bath bombs? Look em up we get em in a shop called Lush here.

Check some stores. You can get all kinds of nice bathtime fun cleaning up.

I googled looking for us stores and found a US site that teaches how to make em:

It depends what is causing the odor. Google "******* odor".

Get shtraight to tha point and tell. Womin say they understand metaphors but they don't. And then take her to tha next coochie-doc. good luck

I had this problem once, i just didn't breathe out of my nose. Couldn't smell or taste anything. I think a subtle approach would be best here. Take a shower and really scrub that bad boy.

Give her a kiss afterwards so she can taste it
