These terms include admirer, transfan, trans* catcher, trans* erotic, transsensual, transoriented, though the final two may be considered offensive as they contain a slur.
The term tranny chaser was originally (and still predominantly) used to describe men sexually interested in visibly trans women, but it is now used by some trans men as well.
A study employing the penile plethysmograph demonstrated that the arousal patterns, genital and subjective, of men who self-report attraction to trans women are similar to those of straight men, and different from those of gay men.
One problem with traditional dating sites, like e Harmony and Match, is that they don't contain appropriate categories for transgender personals, and if they do, often times the labels are still not wholly inclusive.
People who are part of the transgender community may become frustrated by sites that try to fit people into boxes of male or female because it can make it difficult for them to meet the type of life partner or friend they are seeking.
Other tendencies are reported descriptions of being attracted to what transgender people represent (a challenge to the traditional male/female dichotomy) and the explicit focus on the transgender body and appearance: "I like women with dicks. Something erotic about getting fucked by someone who is a woman." According to Jeffrey Escoffier of the Centre for Gay and Lesbian Studies of CUNY, sexual interest in trans women first emerged in 1953, associated with the then famous transition of Christine Jorgensen.
It was after sex reassignment surgery became more feasible over the 1960s that sexual orientation came to be re-conceptualized as distinct from gender identity and cross-dressing.
