Have her go down on you before you stick your dick in.  Make sure to take a shower before she comes over so your crotch smells clean.

After you fuck her for a bit, pull out, and ask her to go down on you for a minute.  She'll go down there, the scent will hit her, and she'll realize that its her, not you, that stinks.

It works, I've done it before.

You beat me to it.

Do exactly this. It really does work. Then your not being rude.

You can also get your fingers up near her nose right after you finger her a little. Shell get it and then youll notice everytime from then on shes all nice and clean
