It depends. I suppose the watch word here is “taste.” If it looks good, it is sexy. If it doesn’t look good, it is tacky, or even gross.
You know what I hate? Those guys who feel the need to wolf whistle at girls with cleavage. Sometimes those bastards make the poor girl walk back and forth two, three times, before making with the air approval.
Most times, as a learned sensitive man, I am able to override my millenia-honed procreation genes, so as to prevent my eyes or neck from turning more than 15% towards female flesh when it would be most inappropriate. Like when you’re having sex, and that chick from the Disney channel is on. As long as you keep it under 15% they shower you with BJs, as is traditional.
Women also like it when you walk up to them at a party and don’t notice their centerpieces that they’ve worked so hard to structurally present. If they have slathered meat in between their legs, or are waving sparklers, continue to look into their eyes and nod. Try not to blink either, studmuffin.
A very special mesasge for the women: when titrating cleavage exposure, consider the axis of tackiness: Is the event an attractor? Feel confident or down? Are their other girls to outshine? Go for it. If conflicting evidence amasses, for instance, Peter North’s Funeral, I recommend venetian cleavage. That we you can signal the young studs semaphore-style, without the pervy old-dudes getting the wrong signals.
