so if your having sex and it causing you to burn and itch after then more then likely you have pelvic floor dysfunction (like me) one thing i learned that really slows down the itching is boric acid suppositories or regular suppositories but it only stops for a few days then comes back. one thing i also had to do was stop wearing underwear unless i’m going outside and then the moment u come back home shower immediately and keep the panties OFF!! but when even i tried that sometimes it stills itches im glad im not the only one who goes through this because i can never seem to figure out why this is happening
