Understanding the opposite sex can undoubtedly be confusing.

There’s a boy code and a girl code, and there are even predetermined lengths of time you’re supposed to wait to call so you don’t come off as a creeper. You may find yourself asking why women are so coy and men so clueless, or why men are afraid of commitment — but have no fear, these questions do have an answer.

Joe Quirk, author of the best-selling book “Its Not You, Its Biology: The Science of Love, Sex and Relationships” will be answering most of your questions on Thursday, Nov. 19 in the Mandela Room in the Old University Union at 7:30 p.m.

Doors open at 7 p.m. and the event is free to Binghamton University students.

“This is an event that all students will find not just interesting but insightful,” Tameka Baber, Student Association Programming Board (SAPB) insights chair and program coordinator said. “They will walk away with both a different and educational aspect to love, sex and relationships.”

Quirk, who is a fiction writer with an interest in science and not an actual scientist, has been praised for his colloquial writing style used to explain love and sex through biological, sociological and anthropological findings.

“This talk is one we have amongst our friends daily. However, I’m excited to hear his answers to the questions we as humans have been asking since the dawn of time,” Matt Reisman, an SAPB committee member, said.
