Masturbation causing penis shrinkage and curved penis

Hi ladies I'm new to this forum but just asking because i have been having problems with the area below the waist. If Im in the wrong area just let me know but recently i have been seeing a urologist for what i believe to be peyronies disease and a small penis. My measurements before seeing the doctor were 4 inches long and about and inch wide. My doctor recommended a penis pump and to star jelqing exercised so I have been doing this daily. Pump twice a day and jelqing twice a day as well. He suggested that i take measurements once a week to follow my progression. AS of two weeks ago i had gained about a quarter inch in both areas. Two days ago I measured once again and found that I have lost an inch in lenght and about a quarter to a half in width leaving me with a weak 3 and a half inches long and little over a half an in in width erection. Is this normal to have your penis shrink before it gets bigger. The main reason i noticed is because my wife commented on its size. She said my erections felt week and small and also appeared that way. Also these exercises have done nothing for my right curvature. They have only made it worse to the point that I nearly point directly right. Please write back with some answers for this is a really embarrasing problem and I fell insignificant standing naked in front of my wife. Thank you for your prompt response. Justin
