My boyfriend has sever spinal stenosis from an injury he suffered while in the Navy. It hasn't been an issue because we hadn't been sleeping together. But now that we are,, or are trying he can't! He can't keep an erection. He doesn't want his Dr to change his medication because he has tried allot of different ones that didn't work well for him. But I'm not sure if other drugs like Viagra are safe in combo with morphone. Or if it is something that can be used long term. He is only 32 for goodness sake. He is really embarressed about this even though he shouldn't be. I was just wondering if anyone has any auggestions or natural remedies for the problem. Or if any one else has been in a similar situation. Thanks!
