What's the difference between the terms "transgender" and "transsexual"? I tried looking it up but I figured I might as well ask here for people's input.
Throwing Wikipedia into the fray...
"Transgender people experience a mismatch between their gender identity or gender expression and their assigned sex.[1][2][3] Transgender is also an umbrella term because, in addition to including trans men and trans women whose binary gender identity is the opposite of their assigned sex (and who are sometimes specifically termed transsexual if they desire medical assistance to transition), it may include genderqueer people (whose identities are not exclusively masculine or feminine, but may, for example, be bigender, pangender or agender).[2][4][5] Other definitions include third-gender people as transgender or conceptualize transgender people as a third gender,[6][7] and infrequently the term is defined very broadly to include cross-dressers.[8]"
Basically transgender is an umbrella term, while transsexual represents a specific subset. This is not to say that people who are transsexual may not prefer the classification as transgender individuals, but the reverse is also sometimes true. Coincidentally most of the trans* people I know tend to prefer transgender as the term these days, regardless of their transition status.
