My husband, Dean bought himself a penile pump without consulting a Dr. Is this safe? What precautions need to be taken? Had prostatectomy.

Here are some ... Once bought it and just use it as instructed. if working, don't leave the ring on for more than 30 minutes, but finish love-making within 10-20 minutes as usual for most men. Meanwhile, it's good idea to seek pro-counseling so to decide the adequacy of every step of care, i.e., the sequencing of care options - drugs to pump to self injection and finally to penile implant. Best wish...
