I am curious here, how's the story ended?

I don't understand why people use this as an excuse to justify pre-marital sex. if you got to the point of marriage, and you found out that your partner has ED, and you run away or divorce him, then I have to seriously wonder about what your priorities are about marriage.

I can help you with that. 

But I'm not any tom d*** and harry. I'm good. 

I do not simply make claims. I offer free trial. 

why does ED mean you'll end up with no sex for the rest of your life? Are you not going to even try to help him through it? Some partner you are.
also, there are worse things in life than ED ... so whether it happens to my partner or not, life could be a hell of a lot worse than "omg ED!"

Two sentences do not a lecture make, thankyouverymuch.

My non-existent experience? and you have experience how? because you read this article? PUH-LEESE!
That's like saying you're an engineer because you finished reading one book about it.
Also, it's either you stand by him or you don't ... what's this percentage?

oh oh oh no no I'm not the greatest woman a man can have, but I at least make an effort not to be shallow like the rest of my gender.

who said anything about you?

In my humble opinion, this impression is caused by selection bias. There are 4 possible scenarios for the development of a relationship.

1. They do not have sex and the relationship lasts a long time.
2. They do have sex and the relationship lasts a long time.
3. They do not have sex and the relationship lasts a short time.
4. They do have sex and the relationship lasts a short time.

From what I've seen, all these scenarios are perfectly possible, and to be frank, I think having sex or not does not impact the length of the relationship.

However, many people have the following perception:

If 1 or 2 happens, people don't think much of it. The couple is happy and all is fine.

If 3 happens, people ascribe the breakup to other reasons, maybe character differences or arguments or whatever. However when 4 happens, people tend to ascribe the breakup to having sex and "use and dump" etc. Now this is obviously selection bias, as there are many possible reasons for a breakup, even when sex is occurring.

Now, the thing is "use and dump" may only consist of 10 percent of the breakup reasons, but people keep focusing on them and talking about them. Other reasons like incompatibility, falling out of love or bad tempers tend to be regarded as "mundane" and not worth noticing.

The analogy is that shark attacks kill less than 100 people every year while asthma kills millions, but shark attacks get big headlines in the newspaper.
