About 3 years ago I fell while working on a scaffold, and was hanging from my harness for about 30 seconds before i could get my journeyman to find a way to help me up. In that 30 seconds it crushed many little veins and capillaries in my upper legs and pereneum (sp?). I get constant cold feel, numb legs, and just all in all poor circulation in my lower body. I talked to my doctor and Urologist and they gave me a whole slew of drugs to try. Ive tried Cialis 5, 10, 20. Viagra 25, 50, and 100. and Levitra, 10, and 20. The only one that works for me is the Levitra 20, and even then its sub par always semirigid atleast but not super hard for too long at all. After 2.5 years of taking these meds, my lil feller is havin a heck of a time keepin up. Im still semirigid almost the whole time during foreplay and working our way up, but it seems the frequency of it getting very hard are lowering quite a bit. Has anyone else experienced this or know if this is a possibility? I remember asking my doctor a long time ago and he said its very highly unlikely, but its seeming like im in that very tiny %. Anyways thanks guys and ill check back in the morning.
