Some people are just never satisfied, as illustrated by a man with an enormous penis who wants surgery to make it even bigger.

Billy-Tom O'Conner is not letting the fact women have refused to get intimate with him on account of his 10-inch member dissuade him from increasing its size still further.

O'Connor said he wants to make his penis into "a monster" and will undergo penoplasty to enlarge it.

He has previously worked in pornography, but this procedure is being done purely for his own pleasure, he told Philip Schofield on This Morning.

O'Conner told the TV show: "On two occasions I have got to the point where [girls have] seen it and they've refused me... they just point plank say they're not willing to go any further with that. But most girls absolutely loved it."

But males left feeling a bit inadequate by this enormous appendage can take comfort from a recent study, which found men with larger penises are more likely to have wives who cheat on them.
