"Anal Sex 101," "Oral Sex 101" and "fatphobia" workshop are among 13 different offerings students at Harvard University have the option of attending as part of its annual Sex Week.

Harvard Sex Week launched Nov. 4 and runs through Nov. 10.

The workshops are organized by the student organization Sexual Health Education and Advocacy Throughout Harvard. Its members did not respond to repeated requests for comment. A Harvard spokesperson also declined comment.

Since 2012, SHEATH has hosted Harvard Sex Week every fall, according to its website.

"Sex Week intends to both educate and advocate, providing a platform for self-exploration and community dialogue," it states. "We intend to promote a week of programming that is interdisciplinary, thought-provoking, scholastic, innovative, and applicable to student experiences in order to promote a more holistic understanding of sex and sexuality."

This year, Sex Week kicked off with "Sticky: A (Self) Love Story" and "Feel Those Good Vibrations: Sex Toys 101." On Tuesday students were offered a sex education class as well as "What What in the Butt?: Anal Sex 101."
