If you smoke, you will notice a drop in your labedo by the time you are around 40. I quit smokeing at 50, by that time it took me quite a long time to get an erection. It has been twenty years now since I quit smoking, Now at 70, I am all dick again, although now, it is with the help of Cialis, and Viagera. I also think that PE helps me maintain a good erection. I have sex about three times a week now. My new Philippineo GF who is 28, keeps me well oiled, lots of lubrication. Sex is great at 70.
