Officially known as the far less catchy ‘anterior fornix’ the A-spot is a patch of nerves much larger than and about two inches higher than, the G-spot. Its main function is sending sexual signals. Touching her here speeds up the whole arousal process. “She will become lubricated enough to have sex in 5-10 seconds and close to orgasm in 1-2 minutes,” says Dr Chua Chee Ann, the sex therapist who reported the discovery in the British Journal of Sexual & Marital Therapy.

How: “Ask your partner to sit with her legs bent and pulled up towards her body before inserting the whole of your index finger into her vagina,” says Fulbright. “Move your fingers past the G-spot and feel for a larger spongy area about two inches after this. You’ll know you’ve found the right spot because she’ll get instantly wetter. The A-spot responds best to light, gentle strokes, rather than the firmer strokes you should use on the G-spot.”
