Just my opinion, but I know I would want to see a dr.
Btw i am a 19 year old virgin
So im freakin out
I know how you feel, I was like that when I was a little younger than you. By the time I was 19 I was in the army and they took care of any embarrassment I might have had. I hurt my back and they put me in a whirlpool, naked, with the cutest girl about my age I had ever seen, massaging me everywhere. Sitting in front of me, lifting my legs and bending them while pretending not to notice the one that was standing up straight right in front of her face. I bet she got a kick out of all us embarrassed guys she had to work on. I could have worn my skivvies but what would that have done? It would have still stood up making them look like a tent and I would have had wet skivvies to wear after, or carry in my hand.
Doctors have seen it all before so you don't need to be embarrassed and that is where you are going to get the answers you need. They will know you may be embarrassed and do as much as possible to relieve your fears.
I would say to decide if you prefer a male or female and look for one you feel comfortable with, or as comfortable as possible.
When I was your age we didn't have any female drs. around here so it had to be a male. However if I need to choose another dr. I think I will look for a female. If I have anything I want to ask about my genitals, my current dr. doesn't examine me he just answers the question I asked. I'm not too sure I like the fact that he won't examine me but in a way I'm relieved that he doesn't because I would feel more comfortable having a female touch me than a male. My wife wants a female next time we have to choose because she feels more comfortable with a female also.
It may be nothing but please go to be sure.
I have this same problem, I just found it today, a black discolouration just below my vaginal opening that was not there before. Has anyone heard about this?? I can't find anything out online, will be going to the dr on Monday....
