Tips please 🙁

I am 19 years old and i am sexually active with my boyfriend. I actually lost my virginity to him and I have never masturbated before. I feel so bad that I have never squirted/cummed because he really is doing an amazing job pleasing me. In all honesty I’m not sure if I have ever orgasmed. What do I do? I also feel its kind of weird for myself to be masturbating and I’m not sure how to do it. Does anyone have tips for me on how to finish? Can someone please help? I feel really down and unconfident because of this.
