Masturbation Tips

Okay, I am 20 years old and my current boyfriend has been the only one to make me cum during phone sex. Now that I know where to touch and how to please myself I just can’t seem to reach my peak to climax with out him talking filthy to me. We don’t get to see each other much and I have a really high sex drive so I want it all day, and he thinks I’m masturbating to much. I have tried porn and it doesn’t quite get me where I need to be. So does anyone have any tips on what I can do to get the filthy talk sensations that he gives me on my own so I don’t have to bother him when it’s my kittens time to be played with?
