Naturally, since TV has traditionally pandered to the male gaze,
In the 55 years of TV watching, I have never noticed a lack of beefcake. Even in the age of "jiggle television" when bras were optional, Steve Austin was running next to Jaime wearing nothing but trunks, Burke and Verdon were working in a field without shirts, Bo and Luke (not to mention Coy and Vance) were chopping wood in just jeans and the images of Ponch gyrating in a fitness class wearing nothing but a speedo is burned into my mental retinas. All aimed squarely at the ladies. Even Gil Garard was "showing the merchandise" for the appreciative in the audience. NYPD Blue had no problem panning down to Jimmy Smit's backside in the show for no apparent plot reason. TV is why I have such a problem with my own body image and never feel good enough. The 70's and 80's were full of well toned pecs.
Oddly, in the same era, Battlestar Galactica was mostly wrapped up pretty tightly (just a few scant exceptions).
and guys think two women kissing is hot.
I'm not gonna deny that was a factor, but it was also the path of least resistance to getting a same sex kiss on the air. Baby steps. Evolution instead of revolution. I'm not sure it matters which sex got the representation first, I guess mileage varies, but after years of negative connotation and coming off the horror of the AIDS epidemic, I'm sure they went with the easiest to swallow. Not even Star Trek did it without sugar coating and they never had the balls to go as far until it was already established (and it had to be on a pay platform).
CRUSHER: Perhaps it is a human failing, but we are not accustomed to these kinds of changes. I can't keep up. How long will you have this host? What would the next one be? I can't live with that kind of uncertainty. Perhaps, someday, our ability to love won't be so limited.
This is more loaded today than it was at the time and says less about humans than it does about Beverly. She was fine when it was Riker's body but once Odan was in a female form, she balked. I would have loved to see him in another hot dude's body and have her say the same thing. Regardless of her dialog, the implication is there if you look for it.
So sure, there are reasons why female / female was broached first, but I think there was more to it than "pandering."
