How can I help him?

Marina❁ • 20 yrs.
I'm the first girl my boyfriend has ever had sex with. We've only had sex about....3 times since we've started dating and he's so good at what he does. The only issue is his stroke. It's not very rhythmic whatsoever and because of that it makes it harder for me to cum, and I think if he had better rhythm it'd feel much better for him too. When I go down on him he likes me to stay consistent and fast with my strokes
My question is, how can I help him? How do I get him in a smooth rhythm? Do you think music would help? I just don't want to make him uncomfortable
