Okay, now we're ready to "DIVE STRAIGHt   IN". But first, test how lubricated she is by gently running one finger along the crease of the labia lips . OH, how good that feels. Do not be put off is she's not sliding off the bed already.  It could mean you may need to prolong foreplay. But, quite often,the lubrication is there, it is just trapped inside.  If you gently insert a fingertip inside the vagina, you can spread the lubrication around (not directly on) the clitoris.
