I find that Yang/Masculine (in astrology fire and air) rising signs tend to be more physically more beautiful, this is generalized (by me) of course.
Air risings are very attractive, in general; Gemini risings is more youthful than 'sexy' or 'attractive.' They can come off cute. Libra risings have great style even if they are supposedly conventionally ugly. Aquarius risings are stunning, even otherworldly beautiful.
Leo risings are sexy. Sagittarius risings are either lanky, or proportionally shaped in their limbs. Perhaps Sagittarius risings aren't facially attractive but their bosomy and well shaped limbs make them attractive. And Aries risings? They can have big foreheads even if they are attractive; but there's a sense that their confidence makes them extremely sexy.
