1.) Their feelings and hormones.
2.) Pragmatic reasons which "Seemed right to me!"
3.) The pressure of immediate circumstances which might make them "Feel uncomfortable as a woman ..."
4.) "I could not stop thinking about what my friends are saying!"
5.) "I was just trying to be nice!"
6.) "I thought that's what I was supposed to do!"
7.) "I didn't know what else to do!"
8.) "This is how it always has been done!"
9.) "I felt God was speaking to my heart!"
10.) "I didn't remember being told to do that!"
Are you sure these are supposed to only apply to women? Because I'm a man, but I'm guilty of pretty much all of those at one time or another, and I know (and know of) of plenty of men who are also such.
I also don't know how much value you'd take this information, but many of the authors of the Vedas were women. One of the greatest modern sages is a woman. So women are just as able as men to be spiritual leaders.
Not to mention, my girlfriend is actually far more masculine than I am.
