Step 1. Grab the nip Step 2. Squeeze and slightly tug on the nip Step 3. You didn't aim into the bucket so it squirted in your face Step 4. Walk away from the nip in shame
The closest I've ever come to milking a cow is seeing one milked on tv. I prefer my cows to be hacked up into meat patties for my burgers.
Apply a lubricant such as Vaseline to your hands to minimize friction. Wrap your warm hands around two of the four teats. Choose diagonal teats (front left and rear right, for example). Or, try the front teats first, then the back pair. Squeeze the base of the teat Squeeze down to push out the milk, maintaining your grip on the base of the teat so that the milk doesn't flow back up into the udder.
I guess that's the reason you are single. This thread is about milking cows and if you consider your Gf a cow then I can't help you.
