about 5 years ago i started using viagra to cure my erectile dysfunction with excellant results. however,during the last year,i have started having more and more difficulty reaching a climax. during sex it feels like two thirds of my penis is numb. only at the top do i feel the same sensations i as used to.if i happen to use a condom,no way i can get to the finish line because i feel even less.
i am add,i take adderall,recently i read where my problem can be related to my use of adderall. if such is true,will a change of medication cure the problem ? or should i seek a natural solution ?
