Natural instincts

[nopussy]

It depends what you mean by "natural" instincts. One common use of that term is that a behaviour is natural just in case we have an evolutionary disposition to do it. In this sense, no, I don't think there is a natural instinct to have anal sex. I'm not sure what benefit anal sex would have had for survival; whereas it would obviously have had several costs. Namely: increased chances of infections (both for the recipient, as sexually transmitted diseases are more easily spread through anal sex, and the penetrator, through UTIs caused by bacteria in the rectum); and significant chance of damaging the anus/rectum (even today, with all the information available, and easy access to lubes, toys, etc, many people still don't perform anal sex safely - our ancestors would have been even worse). So if anything, I expect there would be a natural instinct against anal sex.

If on the other hand you just mean: do some people have a desire for anal sex that they repress due to negative attitudes about it? - Yes, I'm sure that's true. That's the case for lots of sexual desires, unfortunately.

A couple of comments about the quote from Anonymous that you linked to:

because neither find vaginal very satisfying - That's just false for many people. There are plenty of people who find vaginal very satisfying. For many people, vaginal is the primary form of sex. It's the pinnacle of sex. (They're not wrong. They just have different tastes to us.)

you can see the difference simply by studying porn. You can really sense the extreme level of intense pleasure experienced by couples fucking anally whereas vaginal fuckers almost look robotic or bored - To be frank, I suspect that this guy/girl is just projecting his/her own attitudes here. Anyway, even if it were true that pornstars having anal sex look like they're experiencing more pleasure than pornstars having vaginal sex, you have to keep in mind that pornstars are acting. In general, you should be wary of using porn for information about real people's sex lives and sex tastes.

At thirteen, with my very first contact with the porn world, I was quickly way more turned on by anal.

Me too. I've had a preference for anal for as long as I can remember having any sexual desires.

The question is, is it better because it is really better, or because I'm getting the kind of release my body craves?

No sex act is "really better" than any other - we like anal the best, other people like vaginal, other people like oral, some people don't really have a preference - it's just different tastes. It's not that one of these things is "really better" than the other.

From reading around most of the male hang-ups are about hygiene or associations with homosexuality or their ideas about masculinity. If you could strip that away (which is all learned behavior) would there still be some underlying attraction to anal. Who knows...

I can't understand why somebody wouldn't be interested in at least trying it, once those kinds of hang-ups are removed.

Of course it's an instinct! Does anyone really think it's a coincidence that the average rectum is the exact same size & shape as the average cock, that it is normally empty, and that it is packed with nerves that can cause orgasm?

Regardless of one's theory on why, it's pretty clear we're meant to desire & enjoy this.

While there certainly is evidence (such as most of what you described) that could be taken to indicate we are evolutionarily heading in that direction (and to clarify I personally do indeed subscribe to this idea), we're definitely not quite there yet. Otherwise it would be just as easy and natural for the average woman to enjoy anal as it is for her to enjoy vaginal.

It definitely felt like an instinct to me. Anal just always felt so much better and makes me cum harder

We aren't there universally, but there is certainly a subset of women currently for whom anal is much more natural and who instinctively prefer it, which supports the idea that we may be heading towards that point.

For me anal has always felt natural and instinctual to put things in my ass, even when I was a teen. It felt better than pussy sex so even before AO, I had more anal sex than pussy sex. Given the number and sensitivity of the nerves in the asshole, it’s clear to me that anal sex is a natural act.
