Not straight but also not bisexual. When a person is definetely attracted to men/women but they can’t say they are fully straight because on occasions they are attracted to the same gender or they may say they are open to a relationship with the same gender , but this attraction does not mean they are comfortable with the label of bisexual or just feel like this label fits and can’t say they are 100% straight therefore heteroflexible
I have always been with men but i really like this girl/boy and want to date them but i am not bisexual.I guess im heteroflexible
