Well instead of givein each other oral sex at different times why dont u try doing it at the same time so ur both getting pleasure well ur doing it!!

Wow, that is a brilliant idea, I feel stupid for not thinking of that.

The more you push her to do it the more she will back off.

Be a decent man and make sure that 1) you are absolutely squeaky clean - there is nothing worse than having your nose buried in someone's stale crotch.

Then give her decent warning before coming so that she can choose not to have it in her mouth.
It's an acquired taste nd should not be forced upon someone if they aren't happy.
