Here are some ideas to get you started:
Circle of Love: Start slowly by circling the entrance of her vagina with one well lubricated finger. Tease her a little before gently inserting it into her vagina continuing to trace circles against her vaginal walls. Don’t worry about getting elbow-deep, as the entrance to the vagina is most rich in nerve endings, so you don’t have to reach great depths to achieve maximum pleasure.
Come Hither: With your palm facing upwards (toward her abdomen), insert your index finger into the vagina and motion up and back toward yourself in a “come hither” fashion. You should feel her G-spot — a ridge-like area on the upper vaginal wall. If she likes it, gradually increase the pressure as you add an extra finger or two. Woohoo!
Line Dance: Insert one or two fingers into the vagina and press upward on the G-spot. Trace a line from the G-Spot out toward the vaginal opening and then up toward the clitoral hood and glans. Gently circle the clitoral glans and then trace a line back down into the vagina and up toward the G-Spot. Think about drawing a “U‘ between the clitoris and the G-Spot in a smooth, fluid motion.
Never underestimate the power of a slow, gentle touch. It may be exactly what she needs to get all riled up and start begging for more. As she becomes more aroused, you can increase the speed and pressure in response to her hip thrusts and verbal directions.
Have fun out there and always practice safer sex!
