Male prostitutes were certainly a feature of the New York's Tenderloin district, and their existence was famously revealed by the Rev. Charles Parkhurst's 1892 anti-vice campaign:

Every few years, protests would rise to a crescendo, often in the wake of some especially dramatic crime. As recently as 1892, the Reverend Charles Parkhurst — whose attention had been drawn to New York’s low life by a murder in a saloon the preceding Christmas Eve — had become so outraged by the casual arrogance of the then District Attorney in dismissing his complaints that he donned disguise, hired a detective, and set off on an extended tour of downtown dives and brothels. Parkhurst had returned some weeks later to deliver several detailed sermons on Manhattan vice, creating such a city–wide furore that Tammany had closed down half–a–dozen brothels in response.

Parkhurst’s adventures — heavily covered by the press — shocked and amused New York in equal measure. The magnificently–bearded minister had been accosted, in the first saloon he entered, by a teenage girl demanding: ‘Hey, whiskers, going to ball me off?’ and then propositioned by nearly three score girls along one block of Bleecker Street — all of them touting for business within the hearing of a beat patrolman. Later, Parkhurst visited a ‘tight house’ (where all the girls wore tights) and called in at Hattie Adams’s celebrated bordello on West 27th Street, where he was treated to a can–can exhibition that climaxed with one Amazonian blonde kicking away a derby hat held six feet off the floor. It was not until his detective introduced him to the Golden Rule Pleasure Club, a specialist brothel operated by a madam known as Scotch Anne, that Parkhurst flinched. The house, down in Greenwich Village, was located in a darkened basement divided into flimsy wooden cubicles, and inhabited by heavily made–up men in women’s clothing who chattered away in artful falsettos and gave each other female names. The minister, bemused by this sight, had to be taken to one side and told that the denizens were male prostitutes. At this even Parkhurst turned and fled, calling: ‘Why, I wouldn’t stay in that house for all the money in the world!’

There is quite a lot of specialist coverage of the Parkhurst crusade and of this aspect of the sexual underworld. Some good starting points are:

Although it is outside the scope of your original question, London was also home to a number of male brothels and these have been investigated by several able historians. Rictor Norton, author of one key study of the Georgian gay sex scene, wrote a book, Mother Clapp's Molly House, about an early 18th century example, and maintains an excellent web site, full of primary source material, which might interest you, here.
