Eric Decker & Jessie James -- Considering Vasectomy ... But We've Got Cromartie Concerns (VIDEO)

It already happened to one NY Jets star ... now Eric Decker's also concerned about getting a vasectomy because he's worried his swimmers are simply TOO STRONG to be stopped!!!

The Jets WR and his wife Jessie James were out in NYC -- without their 2 kids -- when we asked if they would ever take Antonio Cromartie's lead and surgically shut down E.D.'s baby maker.

That's when Jessie expressed her concerns saying, "We'll totally be that couple like them that gets pregnant again ... we're really fertile."

There's more ... we also asked the insanely attractive couple if they've ever given each other a hall pass to bang other people. Wait'll you hear their answers.

Just one problem -- they're both rich, famous and beautiful enough to ACTUALLY bang their fantasy people!!
