Men and Women were not created equally. Only a Feminist or Feminist Supporter would disagree.
That being said, men and women have distinct characteristics which enable them to fulfill their roles in the world.
As an erudite and distinguished science major.
I would think you would be well aware of these differences (you’ve studied Bio, Psych., and a myriad of other subjects which should have given you crystal-clear insight into human relations(birds and the bees) and relationships.
In a coed classroom guys will 9/10 be more drawn to stare at the girls then visa versa. Yes. Girls will be interested in guys but not the same way and definitely not the same nature as guys.
The Gemara, in reference to relationships, was meant to bring out clear scenarios and if it does so in a very graphic way, then a girl who as LAB mentioned is squeamish won’t enjoy learning it very much -to say the least.
Having studied the sciences and feeling the need to broaden your scope of ascertaining clear knowledge and understanding of Yiddishkeit. I would recommend you find a competent Rabbi that will assist you in your study.
May you continue to strive for understanding and I think a trip to Neve Yerushalayim would be a perfect opportunity to study the Gemara in depth!!!
