Although digital penetration is considered a normal part of foreplay, some guys get overeager and, confuse their fingers for penises. As a result, they finger their partners with a vigour reserved for sex. This also reflects that they have no clue what a woman wants, which is why they have resolved to go hard and fast. Instead, you should aim for a more measured approach; make her get used to the feel of your fingers as you gradually insert more of them. There’s room for intensity, but a little nuance will surely take you a long way.
