Dry desert 🙄🐫🌪☀️ SOS

So recently my boyfriend has been lasting longer then usually because he been rubbing off more in his spare time lol . And now during sex after the first 5 min I am getting dry and he is still hard and after it kinda hurts after 5 min. what can I do to stay wet should I be relaxing more or changing positions in sex? What can I do my self to fix it. Ik i have always love when he ate me out better but sex has just never been amazing with him so I want to make it better but I am embarrassed to tell him the truth is there anything I can do before I have to talk to him.
