The best way to orgasm?

I've been with my boyfriend for 6 months and been having sex for about 3. He cums every time we have sex, but how can I? I've orgasmed with him a couple of times but never feels as good as when I masturbate

I want to be able to have a bigger orgasm with me and more often. He gets a little sad when he can't make me finish because he wants me to feel good. He's my first boyfriend and I lost my virginity to him

How can I help him make me finish because I don't know what to tell him to do
