What if you were reunited with a long lost family member and became sexually attracted to them?  

On Thursday night, HLN’s Dr. Drew talked to Carly and Julie, who say they have had intimate affairs with their fathers after reuniting as adults. They call it Genetic Sexual Attraction.

“GSA is an attraction that happens between family members who've been separated for most of their lives and haven't had the chance to bond properly,” Julie explained.

Check out the video clip above for more details about the women's stories.

Catch Dr. Drew Monday through Thursday at 9 p.m. on HLN, and follow the show on Twitter @DrDrewHLN.
