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.'
Although Caroline, business developer from Leeds who has no children, says she's always enjoyed a healthy sex life, it wasn't until a few years ago that she first discovered her G-spot.
The area is named after Dr Ernest Grafenberg, who first described it in a 1950 article in the International Journal of Sexology, and while many women say it's a highly sensitive, erotic area that provides hours of pleasure, others seem unable to locate it at all.
She told Daily Mail, 'A few years ago, my partner at the time said he wanted to find it. We actually set aside an entire afternoon and spent hours searching for my G-spot.'
'Finding the damned thing in the first place was no easy feat and wasn't exactly the most erotic of experiences, but we got there in the end. I still think that women who claim they can find their G-spot during a one-night stand are lying. Once we'd found my G-spot, my sex life did improve, but I still didn't orgasm every time we had sex.
To be honest, even when you know where it is, the G-spot can still be incredibly elusive. I found it very frustrating.'
Caroline heard about the arrival of the G-shot in the UK from America a year ago, where the procedure has been available for some years.
Professor P. K.W. Dartey, of the UK Laser Vaginal Rejuvenation Centre, London administered the shot.
'At one point, Professor Dartey was trying to locate my G-spot with one hand while holding an 8cm needle filled with collagen in the other.
'I lay on my back thinking: "Oh God, what am I doing here?" It didn't hurt and Professor Dartey was very professional about it, but I can't say I wasn't embarrassed.
'Five minutes later though, I was up and dressed, and to my surprise feeling vaguely aroused, but I think that was more because of the anticipation of the sex that I'd have later.'
Caroline was told she had to wait four hours before having sex, and so spent the afternoon shopping.
'When we did have sex I'm happy to report it was just unbelievable - and it's been the same every time since.'
Caroline is so happy with the results that she's already booked in to have a top-up treatment in four months' time and says she'll carry on having the jab indefinitely.
'I'll treat it in the same way as I do getting my hair cut or my highlights done,' she says. 'Christopher and I always had a healthy sex life, but now it's better than ever.'
The G-shot costs Ģ800.
Plastic surgery and other methods intended to "rejuvenate" the vagina are unproven and potentially risky, the American College of Obstetricians and Gynecologists has warned, but not many seem to care.
