You evidently do not understand much or anything about how the Ebola virus is spread and how it infects people. Once a person is infected with the Ebola virus and starts exhibiting the symptoms of the disease, the disease (Ebola) not being transmittable until after symptoms manifest, they are going to be way too sick and very sick way too fast by the time they are capable of infecting others to be engaging in sex or much of anything else for that matter.
Ebola is not a disease with a very long incubation period (only up to 21 days at a maximum but not proven to be transmittable human to human until after symptoms appear) nor has it been proven to have any sort of or any substantial transmission via sexual activity. Yes, a man who has had the Ebola virus and survived, their seamen and other bodily fluids can still contain the virus for up to 60 days, but then someone recovering from Ebola is going to be very weak and likely very impaired during that time and not very likely to be engaging in sex, hetoro or homo while recovering.
HIV/AIDS is a viral disease that works very differently from Ebola. People who contract HIV/AIDS can have a high viral load and are capable of transmitting it to others long before, sometimes years before the carrier first starts showing symptoms of it. And even when the first symptoms appear, they come on gradually and can be easily kept hidden from others for quite some time.
A person with Ebola is OTHO going to be very visibly sick very soon after onset. They are going to have debilitating headaches and severe body aches, a very high fever, and will very soon start vomiting and have uncontrollable bouts of diarrhea, their kidneys and liver soon start to stop functioning and they sometimes bleeding through the nose and ears as their blood vessels break down.

And so it begins
People have reacted to the disease in various ways and it is the atypical sufferers that we should be worrying about...some don’t get as sick at first and the symptoms not recognized as for what they are(some may even recover). That is why this illness is so dangerous. Even if you have a serious case and a recovery, blood and semen will still carry the virus for several months. Also this particular strain seems to be infecting and killing folks in much larger numbers than previous outbreaks, so I don’t think the facts are fully known about this strain. Given the political filter that the government agencies are straining their news thru, the tendency will be to understate info with an eye towards protecting certain desired voter groups from having their sensibilities violated.
You are citing the main facts, assuming adequate quarantines and controls. Yet certain groups will be at most risk for very bad out breaks and your facts don’t cover the atypical sufferer and we all know there are some.
The Marburg Virus, a related Filovirus, has been proven to have been transfered sexually. One of the original victims in Germany gave it to his wife in this manner. It almost certainly isn't as much of an issue as other direct bodily contact, but it doesn't seem to be "out there" as a possibility, either.
