just look for personals touting or seeking “straight-acting” as a trait, or gay men requesting “no femmes.” Because of the stigma around a “gay” identity, many men attracted to us seek out trans women who are “passable,” or they parse their desire so only the receptive partner in a sexual act is gay, and the other is straight.
I’m not sure this can be wholly interpreted as a behavior of people with an interest in transpeople, but who nevertheless wish to avoid confronting this interest. More often than not, what I see on online personals sections (e.g. Craigslist) is that there is such an overwhelming number of heterosexual men frequenting them, compared to the availability of cisgendered women of a compatible orientation, that men will, after some time of pursuing only cisgendered women (to no avail), give up and settle for an encounter with a transwoman, pretending that the person they are meeting is a cisgendered female instead; in effect, asking the transwoman to engage in heterosexual roleplay with them.
