Sorry I can't stop laughing...ROFLMAO 
 
"The researchers found that many of the women did make noise but not  necessarily while they were having an orgasm. Instead, 66% said that  they moaned to speed up their partner's climax, and 87% stated that they  vocalized during sex to boost his self-esteem."
That's all we need is a study confirming women normally with boyfriends or spouses are acting even when they aren't being paid for sex. 
 "While female orgasms were most commonly experienced during foreplay,  copulatory vocalizations were reported to be made most often before and  simultaneously with male ejaculation," the researchers wrote. Women also  reported making noise to relieve boredom, fatigue and pain/discomfort  during sex."
Hell, they copulate during foreplay. DAMN. I knew I got more and deeper reaction from them during foreplay but I thought that was because I wasn't a sex idol. Now to find out it doesn't make any difference. 
To "relieve boredom". Hell, that hurts. I think I'll get into some heavy ass slapping just to save them from that...because I'm a great big humanitarian. :lol:
FUNNY!
