Can you be aroused by gay porn, but still be heterosexual?

Q: Can you have a fetish for gay porn, but still be heterosexual? ​

---

A: I'm going to assume that you're talking about gay porn where the porn actors are the same gender as you (since most heterosexuals enjoy gay porn where the actors are of the opposite gender from them).  The question of whether a person can be aroused by gay porn and still be heterosexual depends on how you define heterosexuality.  If the term "heterosexual" means only being attracted to members of the opposite sex, then being attracted to people of the same sex (such as in gay porn) contradicts that term.  However, sexual desire can be thought of as being on a spectrum, ranging from being completely heterosexual (only attracted to opposite gender others) to completely homosexual (only attracted to same gender others), with many people falling somewhere in the middle.  It's not uncommon for someone to be primarily heteroseuxal, but to have homosexual fantasies or desires once in a while, or toward a small number of same-gender individuals.  The opposite can be true of people who are primarily homosexual.  There are also people who get aroused watching same-gender people having sex, but don't with to have sex with same-gender individuals themselves. 

​Regardless, you can choose to use whatever sexual orientation label you wish.  It's completely up to you.  I recommend using whatever label (heterosexual, homosexual, bisexual, etc.) that you feel most describes you and your personal desires.
