I Aggressively Pleased My Bf Orally And He Has 9

I aggressively pleased my bf orally and he has 9 thick inches. I always let him deepthroat me and I dont have any gagging problems so I may have let him down my throat to much yesterday. Like I orally pleasured him for 3-4 hours total yesterday. Today my throat is just kinda rough today and wanted to know if there's any remedy other than not letting him use my throat so much.
