I never said Viagra is a remedy for PTSD. I never made the assertion that it's only 100% distributed to PTSD afflicted personnel. I have no idea how you got such convoluted ideas.

What I said is that ED occurs in PTSD patients and patients are prescribed medications to treat various physical symptoms. Is that not so? My information of the connection between ED and PTSD comes from the VA itself https://www.research.va.gov/currents/spring2015/spring2015-3.cfm I can't imagine a psychiatrist would refuse to provide alleviation of symptoms while treating the underlying mental disorder. 

As for PTSD coming from gender dysphoria, that would logically have occurred before they ever came into the military, not, by definition, due to battle in service of the country, therefore a reason not to let someone with such issues enlist. We have enough problems treating service related PTSD.
