My question may seem strange, but I'm wondering if anyone on this forum knows whether penile damage may affect libido? Specifically, if you had a penile duplex ultrasound and it came back showing that you had arterial insufficency and mild venous leak, would this confirmed ED play any physiological role in libido? I'm not taking about the possibility of this leading to depression of the E.D., and this depressed state being the cause of the low libido. I'm thinking is it possible to have physically confirmed E.D. and still feel horny and have a normal raging libido? Does anyone know from personal experience or have relatives that are older, say whether they still have they normal sex drive despite having physical E.D.? Also, does anyone know whether thyroid induced E.D. or prolactinoma induced E.D. could manifest as arterial insufficency or incomplete erection when induced by PGE1 injection? I cannot get aroused mentally, even with porn, and I feel like if I could get mentally aroused the E.D. would go away. Thanks for the help.
