I assume you mean that if you pull back your foreskin your glans (head of penis, knob end) looks swollen? Well, you know what it normally looks like and if it looks different than usual then it might be a good idea to see a doctor. Don't be embarrassed, it is better to be safe than sorry.
No. Most people can't pull their skin that far back
they pull their penis and balls back, if they have big penis its easier to place your penis in between your butt.
You may pull the skin back of an uncircumsized penis (called the foreskin) in your hygiene routine (in order to clean the glans during the shower) or during certain sexual activities. Otherwise, it is not mandatory...
It shouldn't really be driving in the first place.
An un-cut penis, is not having the foreskin on the penis removed either at birth or later in life. You're fine
You need to see a doctor for this problem.
Pull down the foreskin to expose the head of the penis.
No, it is not appropriate to touch a dog's penis without a valid reason and proper handling. Additionally, attempting to pull out a knot is not advisable as it may cause pain or injury to the dog. If you notice any abnormalities, it's best to consult a veterinarian for proper guidance and treatment.
I assume you mean when two dogs are "tied" post-intercourse. If this is the case, then the male dog will be able to push himself out once the penis has un-swollen. This is a natural process and it can take between 15 to 45 minutes. DO NOT PULL THEM APART, since this will most likely cause damage to the male's penis.
It hurts a bit, probably the skin will look red and irritated. Eventually the hair will grow back. If you repeat enough it might eventually stop growing back.
You should not cut it of as that is mutilation It should be able to move right back and forward again smoothly with an erection.
They normally knock you out or numb your penis then simply pull the foreskin back and chop it off with a pair of dental scissors. Nothing to worry about
