Thick midshaft girth

I have noticed that my mid shaft girth looks a little bigger than my base girth. I’ve been on the newbie routine for two weeks now and I do overhand jelq from as the base (I get as close as possible to the base that is). I’m afraid of ending up with a baseball bat shaped penis. How could I fix this? Should I just focus on the pressure on the base more? Thanks a lot guys.

I started out the same way, but after clamping, squeezes, and pumping, my base girth exploded and surpassed my midshaft and then some.
