Burning 🥵 HELP

𝕬𝖑𝖎𝖈𝖎𝖆

I’m 19 and my boyfriend And I get intimate a lot lately because we just moved in with each other. Lately after sex it’s been burning down there. he finishes inside me all the time but now when I go to the bathroom and it still burns. Any home remedies I can try and do to help this money is so tight at the moment. ANYTHING WOULD BE GREAT. ITS UNCOMFORTABLE DURING WORK.
