Dogs don ' t bite you for stuff like that if they trust you . <| sep |> Disclaimer I ' m a genderfluid dude . Having sex with a postop doesn ' t quite classify as hetero sex . Mentally , sure , you can be whatever you ' d like . You can call a relationship straight , gay , or bisexual based purely on mental gender assignment . My boyfriend considers himself bi , I fluctuate against my will and he doesn ' t mind it . Whatever . It ' s all mental garbage that doesn ' t really affect my body , just my mental state . Once more though , I ' m a dude . I have a dick . Even if I consider myself a hot BBQ grill one day , the sex is still super gay because he ' s sticking his XY dick in an XY body . Sex is different . Actual , physical actions are different from mental states . Especially between strangers , like in OP ' s post . In the act it ' s probably more akin to gay partners using toys to simulate functions of hetero sex . The result of a sex change until stem cell research becomes amazing will never be a fully functional sexual organ . The postop vag is a flesh hole with nerve endings basically stuffed into appropriate locations . The person with said postop organ still exclusively possesses XY chromosomes . It will not create a baby , it is made out of a dong , and it ' s definitely not biologically female . There is nothing transphobic about being uncomfortable with the idea of having biologically gay sex with someone you would be mentally considered hetero with .
