What are the best exercises for core strength ?
Patient: besides sit ups, what are the mussels and exercises you need to do to really build core strength? Doctor: Thanks for the query  Looks like you are having a nerve irritation but it wont explain why exactly u are having the pain only while masterbating and not during intercourse. I suggest u use another method like a pillow from next time. If u have no problem getting the erection then u have little to worry  Have a nice living
