Hello, I am a 18 year old male and I have a problem. A couple of days ago, I found 2-3 open sores (didn't bleed too much when I found them, there was only a little bit blood) and what looked like white lesions (I am guessing), almost like blisters but not really "dots" but more wide/long than thick/tall, and I am not sure what this could be. I haven't had sexual activity recently, nor have I ever, and I don't want to tell my parents about this because it's embarrassing (what would I say? I think I have an STD even though I haven't had sex ever?). It is quite painful (I have had worse pain in my life, that's not my main concern right now), I'm just a little scared. Please help me and/or tell me what this could be.
Thanks for any help in advance,
David.
