During sex, my posterior fourchette (the back part of the inner labia) becomes very sore. Like, I can only have sex once a week because I have to let the tenderness and swelling go down. This is a new problem for me, and I'm really frustrated with this change in my previously delightful sex life. The problem is due to friction, but there's no way to avoid it. I've used dilators, plenty of water-based lube, and a variety of positions. My partner and I no longer use condoms (we've been tested and are safe), and we always indulge in plenty of foreplay. I've followed all the advice that my doctor has given me, but nothing helps at all, and I'm really getting frustrated. Does anyone have experience with this pain who knows how to relieve it? I'm currently considering minor surgical options, so if anyone has experience there, let me know.
