Is the emotion of sexual passion a result of the fallen state? (Catholic perspective) I found very good information on this site where the author logically and according to the Catholic teaching explains certain parts of sexual behavior. I agree and practice what is written, just in case if someone wonders if it's even possible. But I don't want to discuss whether the site or the author is correct on the subject so please avoid any comments on the authenticity of the site.

There is a statement:


  Now the emotion of sexual passion is a result of the fallen state, and
  so neither Jesus nor Mary experienced sexual passion or sexual
  arousal.


What is the source of this knowledge or where does the author bases this information from?
The statement given in the O.P. has no foundation in Catholic teaching.

There is nothing wrong with sexual passion per se; however, like all passions, it needs to be regulated by reason. As the Catechism of the Catholic Church states,


  2341 The virtue of chastity comes under the cardinal virtue of temperance, which seeks to permeate the passions and appetites of the senses with reason.
