Need Help Explaining to BF How to Touch My Clitoris?

Dear Betty,
I have been masturbating since a very young child, and thanks to you have progressed from rubbing up against surfaces to touching myself with porn to now preferring my own fantasies with some coconut oil and penetration - these orgasms I have on my own are great! I am 19 years old and am in my first serious relationship. My boyfriend and I have been having sex for 2 months now, and so far has been a good experience.
