Bailey Quarters from WKRP. She started the geek chic in my mind and has never let go.
Barbara Eden (Jeannie)
Catherine Bach (Daisy Dukes)
Barbara Feldon (99)
Jacklyn Smith (Charlie’s Angels, but damned if I can remember the name)
Isis
In later years, when still young and still not getting anywhere near enough sex, add:
Holly Robinson (21 Jump Street)
Those are the repeating characters I most remember. I’m sure there were others.
Agent 99 from Get Smart
Bailey from WKRP in Cincinnati
Julie Kotter from Welcome Back, Kotter (oh how I miss the braless days of '70’s television…)
Daisy Duke, but she was merely eye candy. I knew she and I would never have the meaningful relationship that I could have with the others.
Sabrina Duncan from Charlie’s Angels. You can have your Farrah and your Jaclyn Smith- I loved me some Kate Jackson. Yum.
ETA: Doesn’t ‘oversexed’ mean you have too much sex, and ‘undersexed’ mean you aren’t having enough? Back in the day as a wee prepubescent and early teen, I was definitely not having enough. I mean, any.
YES! I get to be the first to mention Dana Plato from Diff’rent Strokes.
I also had a thing for Lisa Bonet from The Cosby Show.
Two different worlds I tell ya.
We didn’t have a TV in the house so I didn’t start watching regularly until college. But the few times I did see it, I thought John Schneider on Dukes of Hazzard was cute.
Along with Jeannie and Agent 99, a short-lived lust object was
Bo and Luke Duke
Glen Scarpelli from one day at a time
Chachi
Fonzie
Billy Batson from Shazam
Christopher Reeve as Superman
Leif Garret
Parker Stevenson
Christopher Atkins
Alice’s Son (was it Jimmy McNichols)
Steve Austin, the Bionic Man
Ralph Macchio
Man, I watched a lot of TV!
Erin Gray from Buck Rogers.
Oh, you mean Topanga, played by Danielle Fishel. Cory’s “Winnie,” as it were.
Any love for the actual Winnie? Ah, I see that Asimovian has posted about her. So, who’s hotter–Topanga or Winnie?
Dude, I was 40 and had a crush on her. Then my kids dragged me to the Power Rangers movie and I saw that warrior princess and I forgot clean about the Pink Ranger.
When I was a wee sprat I thought Mary Tyler Moore was the most beautiful woman on TV. A local station is showing the old “Dick Van Dyke Show” and y’know what? I was right! WOW! :eek:
Harmon Raab Jr. - JAG
Duncan McLeod - Highlander
Totally forgot Leather Tuscadero. Oh man, my heart melts for some Suzi Quatro.
Mine have been mentioned, but to sum up…
Erin Grey from Buck Rogers and Silver Spoons
Valerie Bertinelli from One Day at a Time
And not mentioned…
Kristy McNichol in The Pirate Movie and Little Darlings (not technically TV, but I watched them a zillion times in the early HBO days when they’d play these movies to death).
David Addison on Moonlighting. I got into the show when it was in reruns on Lifetime when I was 13. I still sort of think of Bruce Willis as my 9th grade boyfriend. 
Wow! Pre-pubescent bi-sexual incestuous orgies! You were definitely the wild child. 
Wonder Woman
Batgirl
Catwoman
Hmmm. Methinks there is a trend here.
You know, I just realized that both of my TV crushes packed heat in more ways than one. What is it about a woman with a handgun I find so appealing?
Annette Funicello.
Barbara Eden.
Lt. Uhura
Oh, yeah, I kind of had my eye on Jo from Facts of Life too.
Grant Goodeve, the older brother on “Eight is Enough.”
