Will my penis will be normal after girth enhancement?

Yes.

The penis will function normally in terms of erection and urination. The angle of the erection may be lower due to the increased weight of the penis, and the penis may hang slightly lower when soft (less retraction).  The penis will have more girth or thickness when soft and when hard.
