Me and my boyfriend fooled around last night, no sex , just oral and with his hand, I was very sore and sensed a little pain while he put two fingers inside, (stretching sensation).. Once I got home I noticed something, beside my clitoris it looked like a dark purple bruise and almost, like chaffed? (Carpet-burned).. Because of past medical incidents, my vaginal entrance is mostly scar tissue, and between the anus and vaginal entrance more towards the vagina I have a tiny red scratch/dot , that is extremely sore, on the biggest scar.. I have had Genital ulcers before and it's a very rare thing called Lipshultz.. No research on it enough to know what, how and when and why it happened but I can't tell the difference if this is just bruising from intense foreplay, or another ulcer ?

Please help me.. I just want to know if it is possible to bruise your vagina and basically carpet-burn it, (or so that is what it looks like).. What are the symptoms, what should I do, and what should I not do ?
