So about 12 months my OH bought some viagra as he was having problems we used two but they didn't agree with him . He went to the doctors and got some tablets from the doctor which agreed with him . A month ago I found the Viagra packet and i noticed that a tablet had been taken out of the blister packet when I asked him he made a flippant comment and I thought maybe I had got it wrong . At the weekend I checked the packet again and another tablet had gone . I asked him and he blamed by 18 year old son ! and then said it must have dropped out . I am so confused as to what's going on and just wondered what others thought ? We have been together 15 years but he has been acting oddly for the last couple of years secrets and rumours but nothing concrete.
