I don't know about the specifics of American men, but I do know that plenty of men in Europe don't have sex, another significant portion uses escorts and prostitutes but usually won't admit it and even claim various 'relationships', and too many men settle for older foids with another man's offsprings out of desperation.

Not to mention that prostitution is largely illegal in USA, which is not the case in Europe, and in Europe prostitution thrives due to unsurpassed demand.
