I want more orgasms

My boyfriend and I have been dating for about two months now, and he has always been attentive and pretty committed to "getting me there." He is actually the first man who has ever successfully made me orgasm (🎉, this was a big deal) but has lately been a little neglectful of my orgasms. The fact that he gets it every time and I don't has been making me sad and almost a little bitter. I know I should just talk to him about it but every time it's on the tip of my tongue, I just can't open my mouth. Has anyone else experienced this?
