Vaginal tearing

So the guy that I’ve been hooking up with recently is on the larger side and I believe I have vaginal tearing from having sex with him so much in the past few weeks.. I didn’t stop having sex with him though and now I have a pretty decent size tear.. what is the best way to take care of this? It was healing but last night I managed to tear it back open so now I’m starting from square one again. I’ve been cleaning it with warm water, icing it, and wearing a pad so that it doesn’t get too irritated.
