Please help. Urethral meatus pain. (With photo)

Hello, I am 20 years old and a month ago I started to experience a burning in the tip of the penis. In addition I have noticed my urethral meatus differently. I have no other symptoms or had sexual intercourse. I even took antibiotics prescribed by a urologist but did not feel any improvement. I have been investigating, since, in these times it is very difficult to carry out tests and it could be a lichen planus or lichen sclerosus but I am not sure. Someone who is experiencing the same thing?
