Squirting!

Hey ladies! I know we've all heard and know about it. I know it comes from the urethra (where we pee from) so I want to know exactly what it is. for the women who have experienced it does it feel/smell anything like pee. does it feel like that small orgasm we all have after peeing when we've held it in for what feels decades. I've read and everything is different but have NEVER experienced one , wish I did.
