Dryness causing friction between me and SO

I have persistent vaginal dryness during sex and this causes pain for my partner and me as well. It’s hard to get into the rhythm when I’m not prepared and it’s painful trying to insert his penis inside me. He hurts too and we’re both uncomfortable.

When sex lasts too long I will begin to dry up and my walls become sore. This leads to further pain as he hasn’t came yet so I have to endure it. Idk he has trouble finishing in certain positions and only likes when I ride. Any other position he complains of not being able to come.

Just now he got upset because I got dry fast after switching positions. He said I took my time so that’s why I got dry. I jokingly said he got dry too as I usually do but he wasn’t amused. Now I think he’s finishing himself in the bathroom and has left me to wait in the bed. Ugh he lasts too long and has too much stamina.
