Why is this question "mostly for the ladies"? Now, Perankh, you've offended me! (Just kidding!)
Is Jonathan Frid sexy? When I was buying all those 16 and Tiger Beat magazines (solely for the DS articles, you understand... certainly not for all those hot and sweaty pin ups of Davy Jones and Sajid Kahn!) I must admit I snickered every time that I saw this "older" man sharing the cover with these teeny bopper/ 20 somethings. With pin ups of Frid on every other page, I was almost tempted to share the mags with my dear old granny. I think, even then, seeing Frid in the unnaturally posed photographs and noting what looked like the grimmacing face of a man afraid, I imagined that Frid must be just as uncomfortable in these mags as Barnabas often was when he was stammering for his next line. One magazine featured Frid, in full Barnabas mode, in about 8 to 10 full color pix, "menacing" a young hippie couple (who were clearly laughing during the shoot), giving the entire spread a sort of "two's company, three's a crowd" comedic look. It was as if grandpa had caught the young'uns kissing goodnight and was about to throttle the hippie boy with his cane.
Still, to all those teenage girls (that I didn't understand then and understand even less today) and all those naked housewives who sent such photos of themselves to Frid, I have to admit that on several occasions I found the character of Barnabas giving me a.... thrill, of sorts. (I'm too embarrassed to tell you which scenes, though.)
But, in general, when I think of DS I usually don't think of sexy people. I think, many of us considered the Collins' our second family outside of the harsh daily reality of growing up in the late 60s/ early 70s. And, apart from a brief crush on a cousin (who had come in all sweaty and hot from mowing the lawn), I don't usually think "sexy" when I think of "family". So, I have to stretch real hard to find someone on DS that I (personally) find "sexy".
Still, "Claude North" beat me to the punch here when he mentioned the tight bell hop suit that Brian Sturdivant wears in Mr. Best's waiting room. Now, THAT was sexy!
