I am not a virgin and I am usually sexually active every weekend. This last weekend my vagina has gotten dry and sore the more we did anything. I thought I had a yeast infection so I took a shower when I got home and went commando for the night after my second night of doing so I started hurting again and then a popping noise came when I turned on my side and I froze then when I moved again another popping noise. Then it pulsed for a few min. It pulsed right after my heart beat. I’m scared that I’m slowing tearing up my vagina or doing damage to it. Is this normal for any women of all ages? Or just me? I don’t want to go to a gyno cause I’m very shy. I only trust two people with my seeing down there and ones my mom. Help pls
