whats the difference?

whats the difference between a girl getting wet and a girl cumming?
or is there none - there the same thing?
if not, how does a girl know when she cums?

A girl getting wet happens before sex or during because she is horny, when a girl is horny, she ejaculates this liquid to make the penis enter more easily. When she cums, it's an intense feeling (most of the time) that you will recognize. It's like you suddenly let go and it feels like a tickle all over your body. Some girls ejaculate something when they come, some don't.
