Hi, Me And My Boyfriend Have Sex Somewhat Regularly But

Hi, Me and my boyfriend have sex somewhat regularly but haven't been using condoms lately but he's always pulled out. One of the times we were having sex it was starting to hurt and then After we stopped I bled for the next few days and waited over a week to have sex with my boyfriend again. The next few times we had sex it was fine until one of the times I started bleeding during sex. The bleeding stopped after a day but still have pain, some itchiness, and also some brown with reddish discharge.
