"  Ever wonder why some guys love giving oral, while others don&amp;#039;t even think about it? We do, too. Luckily, a pair of researchers from Michigan&amp;#039;s Oakland University set out to find the answer to that very question.  They asked 231 men in committed, heterosexual relationships to fill out a survey about their partners with questions about sexual satisfaction and their feelings about oral.  The point? They wanted to find out how oral sex fits into &amp;quot;sperm competition&amp;quot; among men\u2014in other words, whether or not oral has an effect on a woman&amp;#039;s likeliness to cheat.  And the results ended up pretty much like we thought they would: Men with a greater risk for sperm competition\u2014meaning they thought their attractive girlfriends would cheat\u2014are more likely to give oral. Is that the only reason guys do it? Of course not. Some do it because they like it and want to please you. But, if he&amp;#039;s suddenly super interested in going down all the time? You might want to ask him what&amp;#039;s up\u2014he might be feeling insecure.  Want more from Meagan? Follow her on Twitter. "^^<http://www.w3.org/2001/XMLSchema#string>
