How can i guide her?

Ok so this girl gave me head and it was ok but she kept scrapping her teeth on my d*ck so I couldnt get off well how can I guide her how to do it right she isnt experienced at all

Just tell her you'd rather she didn't use her teeth. Be nice about it, or you won't get any mouth-love at all.

Ouch.

you allready asked this question
and it was locked because of an argument
the key to these things are comunication
tell her what you like
also dont pressure her, if she doesnt want to do anything dont make her
everyone is different, and does things differently
so if you want things done to suit your needs you need to tell her, and explain to her what you like.

Please stop changing the question's category once it has been moved.
Thank you.

If you REALLY, truly cared about this girl, you would STOP using her, and actually commit to her!
