The journalist has clearly cherry picked his interviewee to show a very specific side to sex work - she's an independent sex worker who also creates content. This in itself is a nebulous term that basically means she sells photographs and videos too, alongside making herself sexually available for a fee.
Is the interviewee gloaty? No, I don't think she is, but some are projecting this onto her. Additionally, the article itself is advertising, so of course the escort/content creator/whatever it is she calls herself is going to talk about how much she loves sex etc. It is an inconvenient truth that not all women who enter into sex work are forced, neither are they addicts, nor do they work on the streets.
I do think she has a point though, one only has to look at the many threads on here about women who don't enjoy sex/hate having sex with their partners and are no longer sexually intimate in their marriages and expect their partners to be happy about this. I will even go as far as to say that I certain that many of her married clients would have said that their wives no longer have sex with them and they didn't want to risk an affair. I am not saying this to justify sex work, but it is something that cannot be ignored.
Is paid for transactional sex worse than an affair? No, I don't think it is per se, but only if the man can be sure his paid for sexual partner hasn't been coerced, forced, pimped, trafficked etc. And for me, this is the only issue at play here - many men simply don't care about the woman, they're only interested in price and sexual services offered. But, that's a whole other topic.
Ultimately though, it's the man who is looking for sex - the buck stops with him.
