Popped my cherry

What the hell does
popped my cherry mean
I know it's a sexxual term but not a clue what it means

In general, it means to do something for the first time. Specifically, it means to have sex for the first time. Even more specifically, it means for a girl to have sex for the first time, which typically breaks her hymen, sometimes resulting in light bleeding. The cherry is thus popped, as it were.

ah... got it cheers
