Hi karlit I to experience the same thing this is what my consultant has said to me
What you describing is quite normal and due to the fact that the repaired bit does not have the ability to squeeze out urine and ejaculate as a untouched water pipe . there is the chance that things improving but you might never get back to the same force as it was originally. You can apply this milking technique ( squeezing the area in between back passage and ball bag from beyond to the front in a stroking manner after weeing/ ejaculation in order to mechanically milk out the remaining little column of urine/ejaculate if needed.
Hope this helps by the sound of it think it’s the case getting used to it
