The best advice I can give you if anything is this
the quickest way to knock out two birds with one stone will be, follow the newbie exercises dont overdo the girth or fully erect exercises
flaccid stretching and pulling can be done indefinitely, as ive read on here there is almost no way to damage yourself when flaccid and stretching
on a side note, and not being judgemental about anything, but cutting down your body fat has many advantages besides health, along with looking leaner and improving your physique, you can effectively make your penis look longer because there is less fat hiding your penis
to give a brief example I have a friend hes not really fat but just holds it in the wrong places, hes like 6'1 and 250lbs
he is like 6.5-7" non bone pressed, but bone pressed hes at almost 9" even
so if you couple a good diet and exercise with your pe, you will be well on your way to improving many things besides just your penis
good luck
