Is libido the issue?

I’m madly in love. I’m blessed and incredibly appreciative of the fact I have my man in my life who loves me and cherished me. I’ve never felt so loved and embraced from another man the way I do with him. We’ve had an insane intimate connection. Our sex was beyond what i ever thought sex could be. And we had that. The issue is we HAD it. Now, i barely want to be touched. I don’t have any drive. I feel anxious thinking about anything sexual with him because it feels more like a chore. I don’t know where the intimacy went, on my side. Now, my vagina is more sensitive and doesn’t get as wet and usually blows up and swells and hurts after sex. I was never that way with him. What’s going on? Has this happened to anyone???
