Transgender vs Transexual for transfeminine people

What are your opinions on using transgender vs using transexual? Ive been seeing more trans feminine people use transexual to refer to themselves these days and I thought I had it figured out but im confused. Originally, how i saw it was transphobic dolls trying to distance themselves from the rest of the transgender community at large. But the more i read about trans theory and talk to trans women, im finding more and more "cool" trans women calling themselves transexuals. What am I missing?
