fluctuating sizes

i have been noticing fluctuations in both my flaccid and erect sizes WITHOUT any changes in my workout, diet or lifestyle. I'm wondering if this is a normal occurrence and what, if any implications they might have.

it is making it very hard for me to pinpoint the reason and what i need to change to keep my sizes moving in the up direction only.

any feedback is appreciated.

thanks

Your unit will certainly show many different looks if you are doing PE faithfully, but not knowing specifically what you are talking about makes it hard to reply to. What kind of fluctuations specifically?
