A One Trick Pony?

The more I read Jerome, the more I feel as though he is obsessive to a fault over a few very specific topics.  He have only read two (bits of two) letters from Jerome and I feel like he is almost a one trick pony.  He discusses virginity, he discusses wine, he discusses gluttony and fasting, but rarely do we run into anything in his writing that he generally does not connect to one of these topics in some way.  The more read of him the more I find myself thinking "OK we get it, sex bad, wine bad.....".  I get that he is likely trying to really impress upon his readers just how bad these things are, but I feel as though once you have beaten a dead horse perhaps it almost comes full circle and simply makes people all the more curious about them.  He even focuses on specific body parts in his writings, speaking of knees, bellies, and faces specifically more than others, and generally attributing the same descriptive adjectives with them each time, in "paling faces", "weak or broken knees", etc.  He also seems to tend to hone in on specific stories and examples for each of his pet peeves, to the point where he repeats himself, likely in an effort to add weight to his doctrine but instead he seems to me to almost provide scanty proof.  I just find myself getting the end of each reading chunk and thinking "well I've heard all this before, is this really all you've got?" I wonder perhaps if Eustochium had a similar reaction.
