Welcome to HCM
We understand your concerns
I went through your description. I suggest you not to worry much. You are growing up as a man and it is quite normal to have tightness in your groin and testicles area. Bend penis also is normal and it happens to almost everyone. To make a lady happy bend penis is more useful than straight penis. Am I right? Therefore don't worry about unnecessary things. concentrate on your studies.
