While masturbating last night, my labia felt vaguely uncomfortable, but I didn't notice anything incredibly unusual. However, I found blood when I went to the bathroom this morning, and I've been bleeding (trickling drops of blood) intermittently all day. It doesn't hurt, except for some slight burning when I urinate. I'm sure that this is not my period, since I'm a week early, and the blood seems to be coming from the urethra area. I tried to look with a mirror, and I did see blood on my labia, so I thought I might have a labia laceration. However, it could be coming from deeper - I can't see very well, what with bad lighting and nerves (I'm afraid to damage anything further). So my questions are:
Should I go see a doctor? I don't want to explain how I received this injury, but I don't want to endanger myself either.
Also, is there anything I can do help it heal? Will it need sutures?
Thanks for your help.
