Your question is probably more appropriate for comp.text.tex than here, 
but what you're describing is expected behavior. \textrm invokes a font 
*family*, while \textbf invokes a font *series* (and a command like 
\textit invokes a font *shape*). Changing the series does not change the 
family, and changing the family does not change the series. That is, 
\textrm specifies roman family and nothing more -- if the surrounding 
text is bold, so will be the text enclosed by \textrm. Try:

\textsf{\textbf{momma \textrm{mia} momma}}

for an illustrative example.
