I will make this as short as possible. I am a male, I just turned 40 and have avoided being in a relationship for the past 10 years. I have solely concentrated on my career and going back to school. During that time two things have happened; 1) I developed type II diabetes, and 2) I have made a regular habit of masturbating to porn at least once everyday. Here is where I am confused as to what my issue might be. In terms of having real sex, I have not done so in many years, so I have no frame of reference when it comes to how my penis will respond with a real girl. When it comes to the porn, I can get a full erection, but I have to stay vigorous to maintain it, and if I do, I can ejaculate with no issues. When I am alone, however, I can't arouse myself just by touching myself, it just stays flaccid, and this leads me to believe that either one or two things is happening. 1) perhaps the porn has created a tolerance (over time) that wont allow me to get turned by non-porn stuff, and that wont allow me to get a proper erection for intercourse 2) that my type II diabetes has been a problem (albeit, I can get a full erection, so I dont think there is any damage with regard to blood flow and the vessels, perhaps is more psychological) or 3) its a combination of both of the above issues. Finally, does anyone think that Viagra can help me with regards to keeping my erection once I have it? Would I be a good candidate for Viagra? Any and all thoughts are much appreciated, as I am now seeing someone special and I have been driving myself nuts over the possibility of failing when we have sex for the first time (although when I kiss her I start to get an erection and this is with my clothes on, so I think that is a good sign).
