Have I been broken!?

So I have been single for a long time. I recently had protected intercourse with a man who had a huge penis it was 9/10 inches and having sex was an ordeal not enjoyable even with lube. My problem is since then I feel like he has stretched me my vagina doesn’t feel the same. Has this happened to anyone else? I’ve been told before I feel snug down there I’d be gutted if I have been stretched as now I can easily get my vibrator in there whereas before it was slightly harder to get in? Help!!! I’m frantically doing my pelvic floor exercises ...
