Dear, there nothing to be ashammed off and its always good to got to the doctor for a check up once a year to make sure your growing healthy and strong and i would suggest it would be a good time now to get your irritation checked out as Grace says, you might need some antobiotics.
Thank you do you know if there's any home remedies or anything because I'm really uncomfortable talking to anyone about it
You can get bacterial infections on the skin in the genital area. You should be seen and get these looked at in case they require antibiotics.
