Heck, he did it twice. Remember that he and Nichelle Nichols apparently had a brief romance at some point before TOS.
I, personally, could do without half the decon scenes (the only scenes in which it seemed to be dramatically appropriate were when T'Pol, Reed and Sato were "relaxing" after a stressful mission at the end of an episode; during T'Pol's pon farr difficulties; and with Archer's "wet" dream in sickbay...because they contributed to the storyline -- I will not entertain comments about the merits of any of the storyline...I was just making a point about the decon scenes and how they fit within the story), but I certainly have to say that compared to most of the other drek out there in TV land, Enterprise is pretty mild in the "sex sells" department.
I'm with C5; I like the show, and generally gloss over things like JB's catsuit and "gratuitous" decon scenes. They don't bother me enough to worry about it, just like the butt shots on NYPD Blue (although I think they should give us early warning if Dennis Franz's butt is going to appear on screen, so I can avert my eyes and avoid being blinded... ).
