its usually because you have an empty stomach :P
Not always, but on occassion, I have been really hot and had a cool drink that I could feel go way down. I think it's perfectly normal.
I don't feel it. The only time I will feel it,if I drink fast and I get a chest cramp afterwards.
yes i feel that
Yes......I can feel cold or hot fluids when i drink them.
Depends how far you think that is, since your stomach is just behind/below your ribs. Some people think their stomach is where there belly button is.. No, that is where your intestines are!
