My boyfriend performed oral sex on me two weeks ago and inserted his finger and he did it again this past weekend (I've been fingered before with no problems) I masturbated Wednesday morning and later on in the day I felt sore near my opening, nothing major but to help I applied a little organic aloe vera gel before I went to bed. This morning, its still irritated and it seems worse. It doesn't burn when I urinate nor is there any discharge. Near the opening and a little bit above its tender to the touch. There are no funny smells but its just tender to the touch. I looked up all the signs and symptoms of several STD's/STI's and nothing seems to match up with my symptoms. I have no tenderness near my anus, just near my vaginal opening and a little bit above it. I looked to see with a mirror and flashlight and it is a little red but there are no open cuts or anything. There seems to be this white/grey residue. I'm not sure what it is, maybe the skin is scabbing? Also, my lymph nodes in my groin are swollen, so I know I have some type of infection. Am I just irritated down there or should I be worried that it's and STD? All I've been applying to the area is organic aloe vera gel to help with the irritation. If it doesn't resolve itself by Monday I'm going to my gyno. Help!
