there's an orifice designed to take me already, why would i go for anal. if we're speaking intact at least...
i only ever broach the subject of anal with males.
In a sane case, they only go anal if the female's proper opening is too narrow for penetration for some reason. Or if the dog is a male.
But, in the case of a "good" female, they choose anal because it feels different, the tightness, the depth, the texture, everything is completely different. Some people like it better.
I'm not a fan of anal, I've tried it a few times.
It is very difficult and there are few cases when it can be solved well. In order for both parties to enjoy it, it is necessary to have a dog that enjoys anal and has a butt that feels good during sex for ppl and preferably does not leave a lot of dirt afterwards.
With one dog I felt that it was pleasant, she didn't make a mess/dirt and she liked it too, but it wasn't as good as the pussy and she didn't zoom after it like in the case of pussy sex.
With the others, something was not right, the angle, the roughness of the intestine, or I felt a narrow part and I didn't want her to be injured, there was too much poop that rubs the penis and sex from her is not pleasant, or the dog not enjoy it etc.
This hole wasn't designed for that, that's clear.
Maybe male dogs are more likely to like anal, maybe because of prostate stimulation and testosterone with higher libido.
