Here is a fun new Ecchi comic called VITA Sexualis, where the main character has to "merge" or "enter" various girls to allow them to fight with super armor. Weird, I know. But...
In this episode, they introduce a girl that can use the armor without the merging thing... she's a bionoid. So if you are into the biological android thing... check it out.

I think the 9th chapter (the one after this) is particularly cute.

I know people who constantly joke about how terrible and shitty this series is, so I don't think I'll read it

After taking a glance, I think I'll give it a shot after work. Always on the lookout for manga with female protagonists
