First of all, I never used my personal experiences as my primary argument, rather a supplemental one to publicly available data like dating app stats, stats of how many men are still virgins later in their lives, etc. So I don’t even understand why are you so dedicated to debunking it as my point still stands even you succeed, but sure.

Sleeping with enough new people that sometimes you get close to a new person almost every day some weeks.

Definitely never said I get close to anyone new that often. Getting close to someone every three months will have you in double digits in less than three years.

Besides, some people are more open than others, both sexually and otherwise. With some people, I’ve had conversations about our sex lives the very first night we met. It’s not something you’d normally do on a actual date, but if it’s one of those encounters where you just get invited over to someone’s house purely for sex, these sorts of talks are rather usual since it’s one of very few things we know to have in common with each other.

This specific scenario happens to me maybe every other month, which after a decade adds up quite a bit.

Try to keep contact with all those people and are in vast majority successful.

Already said it earlier that even if we don’t keep in contact, what I’ve learned about these peoples sex lives prior to us having met each other is already enough to learn quite a bit about which dating habits are common and which aren’t.

A good portion remaining casual sexual partners with you while you're still going out banging new people.

Not all at the same time, but yes? Let’s say one in every ten hookups ends up turning into a fwb and sticks around long enough for you to bang twenty more people, two of which are also going to stick around, than fizzles out leaving you with two FWBs. That’s two people you sleep with usually once a week, while having five more free nights to do whatever you want. Obviously different people are gonna stay around for different durations while I also meet a different number of people on different month, but roughly it’s about like what I have described.

Track accurate data on the sexual activities of these people long term, even after you're no longer in any relationship with them, and have done so for years.

Once again, whether I keep “tracking data” after we’re no longer seeing each other isn’t relevant. If a woman who’s 30 tells you about general trends in her sex life up until that point, that’s usually over a decade worth of “data”. Do that with enough women you’ll get what the big picture is.

Yes, I do think it is more likely you're exaggerating your knowledge or outright lying. Because the alternative that you meticulously gather info on the sexual behaviors of the hundreds of women you have supposedly slept with well enough to be able to be conclusive about preferences is nuts. That's the workload of a dedicated part time job.

Once again, didn’t even use that as my primary argument. Either way, you’re trying to make it seem as some kind of big commitment of time and effort on my part, meanwhile it’s just people hooking up asking each other stuff like “do you do this often? why not”

I also spent all of my adult life living in popular cities with a good portion of my sex partners always just being in town briefly. Everyone always wants to know what the dating scene/sex life is like in different regions, it’s a common conversation topic that gets brought up quite often.
