HELP WITH SEX SENSATION PLEASE

Maria • 27
Lately my genutals don't feel the same during sex. I had sex the day before my period and my uterus was so low it hurt,. I'm now on my ovulation week and sometimes it hurts but today it didn't feel so good to me. And oral didn't either. I usually love it and can barely take it but today I didn't exactly struggle to keep taking it 😭😭😭 anybody know what could be going on please???? This sencesion thing has never happened to me before!!!!!!
