PC Muscle Exercise Problems.

Dear User,
Here i have few question regarding PC Muscle Exercise:

Q.No. 1.
I m doing PC Muscle Exercise regularly but a few days ago due to some illness i left PC Muscle Exercise then i feel that my penis not erect normally. So what is the remedy regarding this matter?

Q.No. 2.
As per my thinking when a person develop there body parts in routine life then suddenly he left these muscles exercise later on with the passage of time. My Question is that if any body develop the arm muscle very strong by doing some arms exercises then when he suddenly left the arms exercises then he did not feel better strength in his arms. Same as when a person doing PC Muscle exercise in daily routine, but when he left this exercise the Penis strength is not much better is it true. Please do write me. If any body have a sound information about it plz do write me
Thanking You.
