G-shots, also known as orgasm jabs, are becoming popular in the UK.

The non-surgical treatment is supposed to enhance a woman's sexual experience by boosting the G-spot, the ultra-sensitive area of tissue that can hold the key to happy love-making.

The treatment involves injecting collagen straight into the G-spot.

Collagen is a type of protein. Fibrous in nature, it connects and supports other bodily tissues, such as skin, bone, tendons, muscles, and cartilage. It also supports the internal organs and is even present in teeth. There are more than 25 types of collagens that naturally occur in the body.

It makes up about 25 percent of the total amount of proteins in the body. Some people refer to collagen as the glue that holds the body together. Without it, the body would, quite literally, fall apart.

The injection of the protein is believed to enhance the sensitivity of the G-spot and also increases the width of the area.

It also raises the G-spot a quarter of an inch in height, making it much easier to find.

'I have quite literally never experienced anything quite like it,' says 41-year-old Caroline Cushworth, the first British woman to undergo the jab. 'I had constant multiple orgasms which went on for hours.

'That first time, the whole thing was so intense I was actually a bit scared. I was so overcome, but thankfully the intensity is something I've got used to. I still have multiple orgasms every time I have sex, but they no longer leave me flat on my back.'
