Superman being unable to have sex is a fairly common theory.

Sexual intercourse would involve certain involuntary things he would presumably have no control over.

Although it's a bit old (Pre-Crisis), & no longer completely fits the current continuity re his powers etc., "Man of Steel, Woman of Kleenex" explains more on the idea of Superman & sex: http://en.wikipedia.org/wiki/Man_of_...man_of_Kleenex, http://www.rawbw.com/~svw/superman.html
