Long time lurker.
Post COVID, the quality of talent has definitely declined and anyone who disagrees is either being dishonest or has unconventional preferences.
Most men prefer young thin women with long hair, minimal tattoos, and minimal plastic surgery. Think of someone like an Olivia Dunne. Before COVID, these types of providers were fairly common if not the majority.
Post COVID, the average provider is significantly older (25+, if not well into their 30s), heavier, more covered in tattoos, and more likely to have distasteful plastic surgery like goofy duck lips. The quality of service has also significantly declined with agencies and providers still advertising GFE but most refusing DFK and barely tolerating LFK. Clearly, nobody should be compelled to do anything that they don't want to do but they should be honest and advertise themselves as "Non-GFE" but they won't because they know that they won't get any business especially with the current rates. It also doesn't help that there are also legions of simps and white knights who excuse this dishonest behavior and even advocate for clients to earn these "privileges" by bringing gifts or becoming a "regular" to establish rapport with the provider. Rushing clients to finish and outright cutting the hour short has also become common place.
Unfortunately, things are unlikely to improve. With declining birth rates in the Western world, there are fewer and fewer young women in general. And of the few young women that there are, many can make much more money doing "digital sex work" like OnlyFans as others have mentioned.
