So I accidentally ordered high strength viagra(sildenefil 100mg) instead of normal strength(50mg) and I ordered a year supply so now I'm stuck with 3 days straight of hours-long erections every time I take one. I do have erectile dysfunction so it's necessary but now I'm getting sore after fucking my wife so much. I use lots of lube too and am conscientious about friction. I mean I'd hate to waste all this erect time but I get sore after about 5 1hr rounds and then it's ruined for at least a day. I know I can cut the pills in half but that's not the solution I'm looking for. I'm hoping there's a simple way to not get sore and just keep fucking most of the day.
