so just your average questions like how do you do it. will it be fine for both of you. can it be done on males and females. anything to consider so you dont hurt them. can you eat them safley etc etc etc. cause i dont want to hurt them, get scat on my member or in my mouth or anything else yknow
Start off by seeing they're cool with you poking around under the tail to start
(Knowing them good and having a strong trusting relationship is assumed here other wise the farmer finds the body and ponders whether to just burry it or waste time dealing with red tape to report it pending the animal you try to get frisky with)
if they're cool with that start slow, make it all about them (as it aut to be)
get things nice and lubed, and a slight yet steady pressure, if they will go for it they'll let you in, if not things get locked down, start very slow and gentle, for first few times then after that try a few different ways that you'll enjoy, some will like it hard and fast others slow and gentle and every thing in between.
Like every thing, it is a back and fourth till you both find that sweet spot you both enjoy
As to a loaded tube, most don't want any thing there when full, so if she let you before and not now, that is a hint, go for a walk together!
If well cared for (IE proper treatments for parasites and such) oral is safe so long as clean things up first.
Never just ram it in, most any species takes offense to that (Less it is the receiver doing it, had a male donkey sub get impatient he backed into me and drove it to the hilt in him then looked behind annoyed I wasn't doing nay thing, I just gave him a "What do you expect look" at the time it was not "Hawt" it was rather unpleasant for me, once he moved forward so I could lube up things where much better and he was happy as well, as noted by his hard on bouncing away.
Plenty enjoy it, just a manner how it is introduced to them, you make it a great pleasurable experience they will be much more willing to do it again, all you can do is pass the idea and see if they're game, and usually third time based on their actions you'll know if they're doing it out of mutual pleasure or just because you want it. The ones who really want it are absolutely amazing, one mini gelding would squat down on me and flex, the one sub donkey would stay standing but work his tail hole as I came, many good memories from the past, one bull would clamp down so hard when I did the final cum thrust it would make an audible pop when I pulled out, he had excellent rhythm too, relaxed going in, tightened up on going out (how do I know he was willing? renumber how tight he could clamp down when I finished? while if I popped out during, he'd relax to allow me to get back in with ease, not to mention a near 2 ton animal that can total an F150 isn't happy you're going to know it, and he did destroy an f150 he thought was after his cows!)
