Recently, I've been experiencing "fuzzy" yellowish stool.  It's not completely yellow; it's just a brighter brown.  Basically, the stool has a fuzzy and jagged exterior, but I don't feel any pain as I'm having a bowel movement.  Also, recently when I pass gas, a couple seconds after, I feel like a tiny bit of poop is passing out, but nothing comes out at all.

About two weeks ago, I had to hold in a bowel movement for ~2 hours.  I don't remember if this started happening immediately after that.  On the other hand, I think I may have also been drinking less water in the past couple of weeks.  Also, I have been somewhat stressed out for the past week, as it was finals week.

If it makes a difference, I'm 15 years old.
