IMO, it's more of a things guys have to worry about than girls, because of the misconceptions. iM@S either looks pretty "girly" to outsiders, or dodgy (in a pedo-ish way).
Nobody cares that I like iM@S (I'm a girl btw); my siblings like it, and my dad thinks it's a huge waste of money for a "dress-up game."
Sadly, I can't order overtly risqué/sexual things like Dream Club (which I'm trying to get my hands on) for a number of reasons. My dad let me order Catherine and other M-rated games, as I'm old enough to play it -- he probably wouldn't care about Dream Club, either, as long as he didn't see screenshots of it.

My mother, however, would object, so I have to be sneaky. >>;
