So umm a couple of weeks ago maybe a good month or two I had sex with an ex from a while back and it wasn't the best sex but it was okay😐so since we had sex about two days after I began to have problems with itching near the vaginal opening where the penis is inserted. So ever since we had sex it would still itch and it's very irritating.im young so going to doctor my mom would have to attend with me I'm only 17 but i only get the feeling maybe twice a week now instead of on a daily basis.what do u think it is? What should I do?(my mom does know I'm sexually active)
