So much that has been written about hookup culture and 20-something women would suggest that successful young women don't care anymore about love and relationships. That they're not waiting for romance, but assessing their next sexual conquest. As a sociologist who's interviewed several 20-something women on their sexual development, I've found straight young women aren't necessarily embracing hooking up because they're masters of their own destiny, as suggested by Hanna Rosin here a The Atlantic but because they face a new taboo and it's not about sex or money or power. Instead, it's a taboo about that traditional province of women: relationships. Ambitious young women in their 20s feel they shouldn't want relationships with men at this phase in their lives.
