I think you are pretty lucky to have an employer like that, many government departments will go a long way to help, and some private industries, however sadly it is not always the way.
I suppose the reason I'm a source of information is that I've had a lot of time to come to terms with my condition, a series of accommodations which allow me to live a pretty reasonable life.
You asked if I had professional help from the start, unfortunately no. The most important point of what I'm trying to get across is that it is very easy to simply think things are due to one's own makeup. I struggled on for years not realizing I had what is now called PSTD, anxiety and depression and did not have proper professional help until far too late, becoming unable to function properly and being invalided out of my occupation.
As a lack of interest in intimacy was part of my symptoms at the time, and I thought it was just my basic nature, I would not like others to go down the same path, to later find it was not them, but the illness.
I'm afraid Dr Google is all very well. Used intelligently as an adjunct to professional help it is fine. By itself however it can be totally misleading. As an example one can look at the believed causes of flashbacks, nightmares and so on, and even find ways people have tried to deal with them. I do things like this and discuss their accuracy and relevance with my psychiatrist.
What is not fine is to self-diagnose based on one's own perception of one's state and then act on it as if proven.There is a lot on-line dealing with PTSD, anxiety and sexual dysfunction, however I'd not rely just upon that.
Reputable institutions do publish papers and findings, however without the experience and training to see them as firstly reputable and secondly the ability to read them in context one can easily go wrong. An example would be a university which published a paper setting out that a series centered around a teen suicide had positive social value. It turns out that the study was commissioned by the distributor of the series.
