Ain't nothing wrong with a guy wearing a female fursuit! In fact, I'm quite keen on the idea. And I'm sure Mstr.litamacwolf will look perfectly lovely.
However, I've never actually seen (or even imagined) a multi-breasted fursuit before so that kinda took me by surprise. Sorry if I sounded like a hater y'all.
I have to say that my reaction was pretty much the same, and had nothing to do with the wearer being male (I actually didn't notice this fact until Kobuk mentioned it). The idea, while anatomically correct, had simply never crossed my mind, but upon further consideration seems pretty cool. (I think we need to add the puppy head tilt to the list of available emoticons)
On the subject of markings, if you are having difficulty getting an idea of what you want, you may want to take a stroll through some of the art on FA. This could either help you get a firmer grasp on what you want or conversely help you find an artist that could design them for you... I am finding that the creative process behind developing a fursona becomes more and more of a group process the longer you spend on it.
