Good luck and trust me when I say Calendula ointment is and amazing natural remedy!
Have you tried some type of diaper ointment? I am not sure if hydrocortisone can be used internally, double check instructions. Do you have an ask a nurse where you live?
Good luck ☺
Use hydrocortisone cream for the itch. It'll help with any inflammation also. Sound like he may have torn you a bit. I have an itch sometime after I've received anal especially from big ones. Advice for the future is take it slow and use plenty of lube and maintain control of the insertion. When I take my time, my top can pretty much go buck wild when I give him the go ahead.
