There are tons of bodybuilders out there who never really got fat at all, even during a "bulk". They got freagin' HUGE by slowly adding mass, and they did that by eating enough to gain 20lb in 2 months, 40lb in a year, 80lb in 5 years, and 120lb in 10 years.
It's all about consistency and letting the program work. Don't change a thing for now. Chances are that if you do things right (which you're already doing), you'll have years and years of gains to come doing exactly what you're doing.
