London: Guys, you may want to take your protractor in between the sheets as it turns out, the key to making her orgasm every time is all about an angle!

According to a survey of 4,400 people by Lovehoney, Britain's biggest online sex toy retailer, for its Mind The Gap, you are most likely to hit her G-spot at 27 degrees, the Daily Star reported.

Lovehoney sex expert Jess Wilde said: "Men can play their part during intercourse by making sure they hit exactly the right spot to stimulate the G-Spot during penetration - this is at 27-degrees and sex pillows can help to get you both into the optimum pose for pleasure."

The company started the campaign after discovering that 61 percent of women found it difficult to orgasm during any sexual activity.

"For around half of couples this is the absolute peak of sexual happiness, so we are always looking at ways to help them share orgasms together with greater consistency," noted Jess, adding "For women, the key to orgasming easily is to have a strong and healthy pelvic floor, and there are simple exercises they can do to strengthen the muscles in this area."
