You’ll never be able to unsee this creep.

Police released a photograph of a vile straphanger who they say touched a woman inappropriately — and then fondled himself during a subway ride through Brooklyn.

The 25-year-old woman was riding in a southbound F train as it traveled through Park Slope around 5 p.m. Friday when she felt the stranger rub against her upper thigh, police said Tuesday.

The woman moved away from the bald perv — and looked back at him to see he was masturbating, police said. She got off the subway at the 7th Avenue station, while the depraved stranger stayed on the train.

Cops described him as approximately 58 years old, 5 feet 6 inches tall and 170 to 190 pounds.

NYPD’s Crime Stoppers took to Twitter on Wednesday morning to announce a reward of up to $2,500 for information regarding the incident.
