i also think that 2 diffrent heads r better becuz i like it when they fight and freak out when the realize that the are fused together.
i am a fan of the stomach to stomach and the single body (maby 4 arms) w/ two heads.
i like to imagine my girlfriend (hot dark burnette) conoined with either
A) Raven (teen titans)
B} Aska (that neon avalon genesis show)
C) Sakura (naruto)
D) her best friend allie (red head)
E) Carmen Electra ( huzza huzza wink wink)
and whenever i see 2 attractive women really close to each other i image that they are conjoined like that
