this is a great forum and i am here to ask about my issue.

i have been suffering from penile numbness since past few months, i am sitting on pc for hours and julking and milkiing to increase size for hours on daily basis, 

my doctor said i have mild forbromyalgia, sometimes i get muscle pains.but mostly i am fine, i do good on exercise.

oneday

i was sitting on pC for hours at the hard edge of the bed than one day i developed numbness than i immediately stood up and manipulated my penis with hand and it regained sensation immediately but than again i lost sensitivity till now. i need your help in exercises meds etc.i think this is postural/prologed sitting or pudendal nerve compression. i do have errection but premature ejac and not fully errected penis and numbness. thanks

i need some exercises and other advises to improve sensitivity please
