If my boyfriend peep has a smell to his peep and its yellow but mines is clear what can b making his peep like that?

Drinks less water?: The color of urine ranges from almost clear to deep yellow. If a person drinks plenty of fluids, the urine is more clear and less yellow. The urine is more dilute, and will have less of a smell. Sometimes, infections, medications, chemical disorders, etc..., can cause special urine odors. For a healthy guy whose never had urine problems, he can try drinking more water to see what happens.
