Dear Prudence,
I am a bisexual man in my 20s. I prefer women, but I have had casual sexual relationships with men. I’m also monogamous. I am comfortable with my sexuality and realize that it’s fine to be attracted to both genders but to still have a pretty strong preference. My friends and family are also very understanding and supportive. My issue is that I have had trouble telling women I date that I am bisexual. Many handle it fine, but some get very upset. A girl I had been dating pretty seriously for more than a month kicked me out when I casually mentioned it while we were at her house. She texted me that she “had never felt more lied to” and asked, “Why didn’t you tell me you were gay?” These comments hurt me, but I also feel guilty for hurting her. I don’t think that I led her on or lied to her, but I still feel bad that she is upset. How do I bring this up better next time, so that I can fully explain where I am coming from, and how long do I wait?
