Open Question: Can someone please explain what pedal pumping and how it starts?

[feedcrawler]

My husband recently confessed this fetish to me and I feel bad because I really don`t understand it. He says it`s not really a foot fetish but all he needs to see is a foot revving a pedal. Also, should I be worried that he won`t let me be that woman? He says it would be weird for him. Is there anything I can do? He also says he masturbates in his car while revving the engine. Should this worry me? Does this mean he`s thinking of other women while we`re having sex? No mean answers please.
