In the case described in the article the males are obviously getting something out of the symbiotic relationship, but it's nowhere near what the females are getting. I'm sticking to my figurative use of "parasitism" to describe the imbalance.
Seems unlikely.
This is the bargain they've made. It's a rather simple exchange. "Parasitic" is a loaded term here, by applying it you're displaying that you have some sort of political axe to grind.
This was also the sentiment being expressed above, when someone said that what you said sounded "judgmental" -- an accusation that you dismissed by being, or pretending to be, oblivious to it's true intent: "you're attaching pejorative terms to these women, without enough information to make a fair case for it."
It's an obviously imbalanced exchange. We don't take intestinal worms out of the parasites category just because they help us prevent autoimmune diseases.

No, I'm just trying to be objective. If I wanted to insult them I could have called them prostitutes with a single, long-term client.
Sorry for whatever experiences you've had that led to this.
