A celebrity massage therapist is mouthing off about her unusual technique that sees her biting her clients.

Dorothy Stein, 48, from New Jersey, was nicknamed Dr Dot by musician Frank Zappa in the early days of her career when she used her skills to nab free concert tickets and meet her favourite rock stars backstage.

Since then, Dr Dot has massaged - and bitten - an impressive roster of famous names, including one famous band who were 'massage virgins'.

Doctor Dot, real name Dorothy Stein, has built up a successful massage career thanks to her unusual technique of biting her clients. Pictured: Dr Dot biting Elena Pogosyan

Journist Elena says she was surprised at how much she enjoyed her massage session saying that there 'is no way to explain it'

Journalist, Elena Pogosyan, visited Dr Dot for one of her renowned massages delivered with her patented, 'bite method'.

Elena said: 'I was a little bit apprehensive about getting bitten by a woman I've never met. I didn't want to walk into a Fifty Shades Of Grey scene.'

But most of Dr Dot's clients are eager to sample her talents. A certain British music mogul is a big fan. Dr Dot revealed: 'He loves a gentle bite massage'.

Other celebrities demand a more 'sensual' approach. Dr Dot says that one female rockstar demands that she is massaged all over her front, although Dot adds, 'I've never bitten boobs though.'

Dorothy made her first forays into therapeutic biting at the age of five, encouraged by her 'hippy' mother.

She said: 'She wanted me to massage her but my hands weren't strong enough, so she just kept on saying 'Bite me! So I've been doing this my whole life.'

Dorothy, demonstrating her technique on Elena Pogosyan, used to give out free massages to big rockstars in order to get into concerts without paying

At 15, Dr Dot gave her first backstage massage to Sheffield-born rockers Def Leppard.

She said: 'I wanted to get into shows for free and meet the people who wrote the lyrics that were so close to my heart.

'It was a choice of either money or massage. So I chose massage.'

Since then, Dr Dot has traded her services to see over 3,000 concerts for free.

Giving free massages helped build her reputation, and she now charges around $150 (£102) for a massage session - with no extra fee for biting.

The colourful masseur told Refinery29 how she has practised her biting technique on Sting and Simon Cowell.

She says: 'Naturally, I ask the client if they want to try it first. And then - before adding any oil - I bite the whole back up and down, in a very fluid motion, bit by bit, avoiding any bones. I do the neck and shoulders, and sometimes the glutes, too.

'I take big bites, obviously not firm enough to break skin, but firm and deep enough to grab and "tenderise" the back muscles, warming them up for the real rubdown that follows.

'I’ve never hurt anyone doing it; it’s actually divine for the client, as it’s a sensation they’ve never experienced before. They’re marching into the unknown and putting their trust in me.'

'I'll never forget this experience because it's not every day I have a woman biting my back

Elena was certainly surprised at how much she enjoyed it.

She said: 'It felt like someone biting my back - there's literally no other way to explain it, but it feels good.

'I'll never forget this experience because it's not every day I have a woman biting my back or my neck or playing with my feet or biting my butt.'

Dr Dot usually starts her sessions with biting - she describes it as the 'appetiser to the full meal'.

She bites their backs and buttocks, before rubbing oil on their skin and moving on to a more traditional massage.
