A trans man may be gay, bisexual, pansexual, polysexual, asexual, demisexual, etc., and some trans men consider conventional sexual orientation labels inadequate or inapplicable to them. The literature commonly indicates that sexual attraction to those of their same gender (e.g., trans men liking men and trans women liking women) is considerably less common among trans men than among trans women; the vast majority of trans men are reported as heterosexual. Surveys from the National Center for Transgender Equality show more variation in sexual orientation or sexual identity among trans men. In NCTE's 2015 Transgender Survey of respondents who identified as trans men, 23% identified as heterosexual or straight. The vast majority (65%) identified their sexual orientation or sexual identity as queer (24%), pansexual (17%), bisexual (12%), or gay/same-gender loving (12%).
