I am 19 year-old man, i am suffering since about 4 or 5 moths from something strange, my penis became fluffy and my testes i can see that they are small, and i became so easy to be sexually excited, even by only thinking in sex, i remember that in the past i was watching pornography but i was stopping my self from masturbating even when i was very excited, i do not actually know if that was the reason for my current situation, i live in a country that has no sexologists, so i hope any one here help me indintify the reality of my current status, and if my last actions is the reason? , and also if my situation could be fixed? , and thanks in advance
