Here is some Emacs Lisp that I think does what you described:

(defun foo (re)
  (interactive "sRE: ")
  (while (and (re-search-forward re nil t)
			  (= (- (match-beginning 0) (point-at-bol)) 0))
	nil
	)
  )

Being a novice at programming and Emacs Lisp that might not be the
smartest way, not even a particularly good one, to write such a function.

Another possibility is to put '.+' in front of a regular expression to
exclude matched-strings at the beginning of a line.
