The looks, smells, and even sounds that your partner makes play a huge role in attraction.
In short, most people want to get with someone they're physically attracted to, and bisexual people are no different.
Research involving bisexual men found they are attracted to the qualities stereotypically seen as attractive in men and in women. And those qualities differ depending on the gender of the person being considered.
For example, a bisexual person may be attracted to males who are tall or have a masculine appearance, and women who have small waists and larger breasts.
"Some bisexual people may find themselves attracted to different traits in men compared to women," Ogle said.
Others may find that they're physically attracted to the same type of look (masculine, feminine, androgynous, or others) no matter the gender of the person.
