[I write this in the expectation that the female view will be given in response.]
Our senses are sight, sound, smell, feel and taste. It is difficult to arrange those in the order that they appear in sexual arousal to completion. Usually I am attracted to a woman first by the sight of her, perhaps though first by the sound of her voice, smell of her perfume or natural pheromones. Always feel and taste has followed later if any contact at all is made.
I am drawn to a woman with an attractive body. A pretty face is a beginning. A pretty face is one well-shaped, nice eyebrows, eyelashes, clear even glistening eyes, an aquiline or unusual nose, defined cheekbones, full lips, well-formed teeth preferably white, not discolored, and a firm chin. Her ears are inviting, well-formed; neck slender; hair of any color obviously clean and cared for well. She has an hour-glass figure - larger at the top than the waist and broader in the hips than at the waist. Her arms are slender, the biceps larger than the forearms; hands soft appearing with thin, long fingers. Her thighs are larger than her calves, her thighs, knees and calves make contact in between them. Her feet are on the smaller side. Big tits nor a fat ass attract me, but firmness of both is a plus, as well as distinct rounded buttocks defining her definitely as a woman.
Her voice will be distinct, not tinny, but in the range expected of a woman. A slightly husky, I might even say lusty voice is a plus. She will smell clean, perhaps even sweaty if she has been exercising as in walking, running or working out in a gym. Her perfume or cologne will be subtle, not overpowering. Better yet her natural pheromones will exude sexuality.
I will want to touch her. I like touching as I talk with a woman if she is willing. If I touch her I expect to feel soft yet firm flesh on an innocent part of her body, like her arm, shoulder or back. Feeling, perhaps seeing fine hairs, for example, on her arms enhances my interest. Fine hairs on a woman's belly, buttocks drive me wild with lust.
