I recently had intercourse recently for a long duration of time, i know i should have been lubricated but by the fourth or 5th time of having intercourse my vagina was raw and in pain...i just happened to look at my vagina today and noticed a bleeding cut on my labia minora im guessing this is from the non lubricated sex and the fact that i carried out the act for so much longer while still in pain...how can i treat this cut?
