squirting

Hello,
My boyrfirend and i have been trying to acheive the g spot orgasm.... i know he can find the spot.. and i think we've gotten close... we've gotten to the point that i feel i might pee... but it never really goes any further...
so i'm just wondering what its supposed to feel like? Is it much like a clit orgasm??
Any info or tips would be greatly appreciated!
thank you for your time!!

My man is amazing! Last time we had made love, it lasted off and on ( including a couple times in the middle of the night and early mornin), for about 12 hours. He made me cum 11 times, yes we keep count. However about 8 of those times i experienced for the first time female ejaculation .. it was awesome, but i didnt know my body could do that so many times in a row. How could this be possible?
