HELP!!!!

️E
My vagina feels like it's become loose. When he goes deep I don't feel the same feel as I used to. Actually I don't really feel his dick in me most of the time. I've been trying the kegal exercises and we've waited a week to have sex. I still don't feel much. Please if you have any tips please im begging you to text back. My man feels like he's not good enough. But it's just me. Please help. I don't want to spend much money either
