so maybe I overdid it this time. (I feel like such a perv. 
)
In regards to the orientation of your interest, specifically in pregnancy for fictional characters, you shouldn't feel like a pervert. It's just a personal interest, no more and no less. Perhaps it's more exploring a concept of life through a safe and innocent medium? Such a subject is not so easy to explore in real life as real life has consequences that fiction does not. Who knows? Perhaps you will know exactly why some day? Ultimately it matters little the "why" in the future, as the current "now" shouldn't leave you feeling awkward about it.
It's nothing to be ashamed of, it's how we grow as individuals. That interest can be held in common amongst others, but no law or rule states that it must be this way. Even if such is the case we're still all unique one way or another.
On another topic, I don't plan on ever making pics of pregnant anime girls myself and I still have "standards" when looking at such pics (although recently I've stepped over those "standards" a few times). I've got to cut back on looking at pics of pregnant anime girls before it consumes me.
It only "consumes" you if it takes up every moment of your life (both waking and otherwise). Try not to chastise yourself over thoughts that are absolutely harmless. It's only when an interest strains your
good relationships with others and engulfs
every aspect of your personality that it becomes an issue. Enjoying something, even iDOLM@STER for example, is healthy and distinguishes people from others. People enjoy it on different levels and they're absolutely entitled to. None are inherently wrong, nor should those views be shunned or shamed by anyone. Standards shouldn't apply, and they really don't with all things considered.
It is what it is, and that's all it is. That's how it should be for personal interests concerning only the individual. You seem like a good fella Sunflorazumarill... so just be yourself and don't sweat what you dig. It's all good, as it should be all good.
