Do I have Crabs or Pubic Lice? - constant pubic itching -lice -crabs

I am a teenager, I never had sex, but I think just about my penis itch in my pubic hair. I have not seen bugs crawling or something. Scabies is not constant, but sometimes I get a burning sensation. It generally starts after taking a sleep in the night before the shower. but any other part of the day, I am right or no amounts of itching. I do not know if I have cancer or not or if it is normal for my pubic area itching. As I said earlier, is not constant, but is rather relaxed. and so it is a way to really see if I have crabs because they are clearly visible? or are difficult to detect?

PS - you do not seek answers, "a doctor"
