Is it just me?

Hey guys so lately i’ve been thinking that my vagina doesn’t work or is broken in a sort. for some reason, after one round of sex i be completely okay & satisfied. going again, actually will begin to hurt. the more i have sex after my body is “done” the more it hurts for me. iknow when i’m done because my body gets weak & shuts down, my vagina shuts down as well. idk but i really do wish i could be the girl that can go rounds!! i’m not understanding why i think i have a problem lubricating. i’m more on the creamy side but for some reason my vagina doesn’t just stay soaking wet during sex , it’s like it dries out. HELP???
