Im only 17 years old, I first started having sex at 15 and continue without condoms with the same partner, he is the only guy iv ever had sex with but hes had sex in the past with many other girls, but as far as he knows he doesnt carry a disease, his partners were all under 18 with im guessing minnimul partners, although he hasnt been to a gyno. A few months ago my boyfriend pointed out that there was a purpuly brown spot near the bottom of my labia, on one side right near the opening, I just thought nothing of it at the time. Last week I looked closely with a mirror and saw a distinctive skinny black streak, as if it were drawn there with ink.It is only on one side it isnt raised the skin feels exactly the same as the rest, and it doesnt hurt at all, no discharge, nothing abnormal other than the colour and the fact that it might have grotten a little bigger and changed colour slightly over a few months. Iv been reading alot on the internet about vulvular cancer, melanoma, you name it, and im getting worried, alot of the sites say I should check this out right away and it sounds like it could be very serious but just not progressed to the point of having serious side effects, because other than the colour I feel fine in that area. I have been getting abnormal pains in my chest and neck area not real painful but enough to notice. And iv read that the cancer can effect the lympth nodes, so where are they!?, and if it does then your life expectancy goes way way down, but almost every case is with women over 40 so I just dont know what to think , im going to get this checked out as soon as I can. I really would like to hear from someone about this soon tho because I cant wait, im real worried, so if anyone knows anything about this black streak please let me know
