thanks to all of you guys for all this - everything is helpful at this point. i went to a specialist yesterday who was just as perplex as i am, but i'm getting blood tests done today and going back next week for a rigiscan (the nighttime erection test) and if necessary a doppler after that.
fuzzy ken - can those endocrine levels be determined by blood tests, or are they something i need to request myself?
Great topic, abcd1--I'm glad you raised it here. When your blood is drawn for routine testing (physicals, etc), the analysts don't automatically look for everything. So your MD would have to request specific analysis to look at endocrine levels. But if you went to a specialist for EDs, they would have done this. You can confirm and ask them specifically if they looked at x,y,z when you get the results.
I liked the precise way that fuzzyken addressed the physiological side of ED. When it comes to the behavioral side, here is another question. Some guys naturally compartmentalize sex and emotions. One is completely independent of the other. These are the guys who can have a hard time telling you how they feel if you ask them, and can be oblivious to emotions, which is a plus in sports or the military. If you have that kind of temperament, I suspect that would increase the chances that this is more physiological or biological in origin.
But other guys have more integration between the emotional, sexual, relational, personal worlds. One influences the other. I am definitely in that group. I've never had ED, but my emotions definitely fuel my sex drive. An intimate conversation about a completely non-sexual topic with someone I love can make me get aroused and drip all kinds of pre-cum, even if I don't get fully hard or feel like having sex. I can also see a porn star in person and be completely indifferent about having sex if there are no emotional or personal drivers.
If you do have a temperament anything like that, in which your feelings/emotions trigger sexual responses, then the advice about exploring the personal/emotional/behavioral/relational components of sex is also good. It's not at all about being crazy or needing a shrink in those cases. It's about understanding the triggers, and understanding how and why you need to feel a certain kind of comfort, security, openness, trust, etc., or even a certain kind of reciprocity, before you can relax enough to let the stream go.
That kind of analysis is about about understanding how your brain also works with your body to shut down or start up behavior. So both approaches, looking at endocrines/physiological things and looking at social/personal things, are very complementary, and will give you a more rounded picture than pursuing one or the other in isolation.
Great topic though--good luck with the research & investigation. I am positive you & your team will figure out what the issues are, and get them resolved.
