So I'm new at discovering this part of myself. I've been getting small orgasms when using an electric toothbrush, but I decided to try getting a clit-sucker because I've been hearing great things about it. Maybe I still have to learn how to use it, but is it normal to feel it's too overwhelming (in a slightly painful way) even on the lowest setting when used directly on the clit? Is there a better way I should be using it? I usually don't use the toothbrush on it directly either. Are there better toys that can replicate what a toothbrush does?
