Sex with Trump 'may have been least impressive I’d ever had': Stormy Daniels

The revelation is made in her upcoming book Full Disclosure.

The book will only be out on October 2 but the Guardian newspaper, which put out the story on the book Tuesday, said it had got hold of an advance copy.

America will hold midterm elections in November and Trump's popularity ratings are currently lower than any other US president at a similar time in their presidency.

The low approval ratings also have the Republicans worried that they might lose control of both houses of Congress. And should that happen, that will mean even more legal troubles for Trump whose 2016 presidential campaign is currently being investigated for possible collusion with Russia.

There has been talk of an impeachment.

“It may have been the least impressive sex I’d ever had, but clearly, he (Trump) didn’t share that opinion," the Guardian quoted Daniels as writing in Full Disclosure.

The Guardian added that Daniels writes in "sometimes excruciating detail" about Trump's genitalia in the book.

She mentions size, saying it is "smaller than average" but not "freakishly small".

And she says that Trump knows it is "unusual".

“It has a huge mushroom head. Like a toadstool…"
