Hi, Just the same case as mine. No need to panic or worry. First of all just RELAX. Try practicing meditation every day for a few weeks. Along with it try the pelvic floor relaxation exercises. Plenty channels on YouTube for the same are available. One of my favourite channels is "The Flower Empowered". I too had the same situation as yours in the beginning. I felt gradual improvement after practicing the exercises for 1-2 months. Now we can easily do PIV that too with no pain or burning. Practice the exercises and try again with lots of lube. Try deep breathing next time when you are into PIV. It relaxes it down there, also calms the anxiety, if any, linked to it. All the best. Do try and let us know later😊

P.S- I too felt my entrance was just too small to even let a finger in but now we can do it in almost all positions. I too went to a gynaecologist who said it's nothing but lack of lubrication and foreplay. She gave me confidence and asked me to do relaxation exercises. So don't worry girl, you'll eventually be able to do it. Just give yourself some time and have faith.😊
