Lichen planus. Looked on my glans penis!

Noticed a simple ring sore on my glans penis which was very mild 3 month ago and the affected area pained mildly when touched, I thought may be due ti friction the skin is coming off as I am sexually inactive and have had zero sexual experience. But two three days ago I noticed that the size of the affected area has increased almost to 1/4th of the glans penis,that portion has become leathery and a little hard and I can't feel the flesh when I touch it! It also pains sometime! I applied some moisturiser hoping it would help but the condition remains the same! Then I was a little worried and googled the symptom and did a little research about various sexual and asexual skin diseases, the images of LICHEN PLANUS were exactly the same it looked on my glans penis!
