#1 A woman's breast swells up by 25% when she is turned on

Called introitus or orgasmic platform, a woman's breasts can increase in size by up to 25%. Blood flow to the area around the nipple will also increase, and nipples can end up looking less erect.  

#2 Many men can get turned on simply by a woman's voice

Of course, the breathier and sexier the voices, the higher the arousal. However, believe it or not, men truly can get turned on simply by hearing the voice of a woman.
