HEELP

I'm new to blowjobs like I have never done them, he actually told me what he liked (the second time I did it) but since I'm new to all that I think I didn't catch the message... recently I thought he liked just because he grabbed my hand, was more affectionate and when I stopped he got surprise (he never did neither of the three) but when I asked him he told me he felt nothing and gave me some more tips... I'm not gonna lie I felt dissapointed, but the point here is HOW DO I MOVE MY TOUNGUE? LIKE I THOUGHT I WAS DOING IT RIGHT BUT I GUESSS NOOT?
