I think many people like m/m for its own sake, just as many people like het, femslash, polyfic, and gen for their own sakes. I don't see anything in that to beat yourself up over.
If you're having difficulty writing fic about female characters and want to change that, consider which fandoms you've been writing. Are you writing fic in fandoms you were drawn to because you like the female characters and their relationships, or are you writing fandoms you were drawn to because you like the male characters and their relationships? If the latter, no wonder you haven't been inspired to write fic involving the women.
There are plenty of het-focused fandoms out there if you want them -- probably the majority of the fandoms in existence are het-focused. There are also many femslash fandoms, and a handful of OT3 fandoms. (Have you considered Haven? SFF series with a female star and popular f/m/m OT3 with all sides of the triangle fully developed in their own right.)
