Gagasexual 

A sexual orientation in which sexual arousal can only be achieved in the presence of Lady Gaga.
This includes being near Lady Gaga, pictures, video, music, thoughts, etc.

Either a male, female, or hermie can be Gagasexual.

Because Lady Gaga is a female, male Gagasexuals may be considered straight but most preferred to just be known as Gagasexual.

Person 1: Hey are you gay, bi, or straight?
Person 2: O I'm Gagasexual...Only Lady Gaga can turn me on.
