sex hurts too much

everytime i have sex with my boyfriend it hurts and burns wayy too much afterwards, when i pee it burts, but like 2 hours later the pain goes away and i don’t feel it again until we have sex the next day and i don’t know what to do, idk if its because we have rough sex or his member is too big or what,

edit: i’ve gone to doctors before they tell me its yeast or uti and i take the pills but it always comes back :( i’ve been to like 4 different doctors
