Gotten lazy during sex

Don’t get me wrong my partner turns me on a lottt we used to have great sex 24/7 I rode his dick but on occasion not all the time. Anyway we had a baby things calmed down and I feel like I’ve gotten lazy. The sex is great don’t get me wrong but I’d love to ride his dick, make him feel good. I’ve just forgotten how and it’s just so much effortttt in my legs.

Any tips and tips for riding it ? Thanks
