You’re basically describing a straight woman’s attitude about women. They appreciate the female body and can say how attractive/gorgeous/sexy/beautiful another woman is without worrying about whether or not that makes them a lesbian. It’s appreciating good looks! It makes no difference if it’s men or women! You can appreciate beauty without needing to fuck it.
Unfortunately this is very much a stigma society places on us. If you’re gay, you can only find men having sex hot. If you’re straight, you can only find a man and a woman having sex hot. If you’re a lesbian, you can only find two women having sex hot.
That. Is. The. Dumbest. Bullshit. Ever.
Gay men appreciate the beauty of women and, often, in the media, they’re the main ones critiquing them. Interesting hypocrisy there, hm? They’re not sexually attracted to women, but they’re the “foremost authority” of fashion and beauty in the media? But wait! They’re gay! *gasp* Horrors! They should be repelled by women! How can they know who’s beautiful and who’s not? They’re supposed to think they’re ogres because they don’t want to have sex with them!
Do you see my point? Why is it any different for you to appreciate the hotness of a hot guy? You don’t want to have sex with him, you just know he’s gorgeous!
Acknowledging good looks means you have eyes. It has nothing to do with your sexuality.
