Sorry to hear it didn't work
But you know, you can keep trying and playing around with that little spot.
Just like us women have to learn what spots to hit, (believe me, I am constantly learning where my husbands are!) LOL just the same with men, you don't always get the right spot the first time around....give it another shot sometime or many times until ya find it
OK I had to edit this because I just had a thought about that spot. Try using your fingers. My husband will use his and hit it everytime! If he uses his tongue, it doesn't always work. So,use your finger(s) first and watch her reaction.
