Two swollen areas on my vulva. They look like blood blisters. One of them actually bleeds a little and the blood looks like it may be slightly pus-y though I'm not sure if that wasn't just due to where the blood was coming from.. I put Neosporin on them after my shower. Have recently become very sexually active (monogamously) and wondered if the added frequency could cause this. They don't hurt really. Color is normal around the vaginal area and there is no discharge or odor. Any thoughts?
