It is possible, but would be very difficult.
the same as you would finger any other girl. it's best to rub her clit and go down slow then put your fingers in, best if you use two. unless she is tight, then introduce the second finger slowly.
Assuming that 'cold' means normal room temperature, then heat would flow from your finger to the water.
Maybe because either it is not real silver (in which case the ring would start to turn a coppery colour after a while) or because you are allergic to the metal. Or it could be that it's too tight. My gold ring (I am not allergic to gold) is starting to leave a blue mark on my finger, but I think it's just because the ring is a bit too tight.
Quite often it is necessary to have the ring cut off of your finger. In some cases it is necessary to have it done by a doctor.
I would suggest talking to a doctor about it you may require surgery if it is actually deep enough
It would depend on if finger inserts are used in the ball. If inserts are used, simply replace the inserts with a larger value. If inserts are not used, use a bevel, scraper or sand paper to open up the hole.
If you put your finger into a pencil sharpener you will explode and die.
The most expensive finger as far as replacement would be the middle finger. This finger has many ligaments that would need to be microscopically operated on in order to attach the finger and get the best use out of the hand.
Wherever you would select a movie, hold you finger on the desired movie for about 2 seconds and slide your finger left. A red box reading "Delete" should appear. Touch that and it's gone.
There is no finger that would indicate a lesbian.
Why would you eat your finger? That is just weird. No you would not grow it back.
