What does it smell like? Any discharge or excessive smegma? If it smells fishy and there is a white discharge or excessive smegma build up everyday, then you probably have a yeast or fungal infection under the foreskin.
If not, and the odor isn't raunchy, then you're probably fine. There will always be some odor under the foreskin and around the genitals. If you wash daily, it shouldn't be an offensive odor. But trying to get a completely odor free penis is nearly impossible. But if you're noticing an odor from like 2 feet away, there is a problem.
If your unit normally points downwards towards your testicles, it could be that after you urinate, a few drops may leak out. Being uncircumcised I had that problem and I noticed an odor and I went to the doctor. My foreskin was tight and no matter how much I tried to squeeze or shake everything out, sometimes a little dripped out afterwards on to my testicles. Much to my surprise, you really sweat a lot in your groin area and that's the smell I had. My doctor was most helpful and I found a little powder on my testicles each day would keep them dry and help with any dribble throughout the day. Eventually I ended up getting a circumcision as my foreskin was too tight. Hope that helps.
Gardnerella will make a clean penis stink. A trip to the doctor might be in order, to get the right antibiotic to get rid of it quick. I doubt this has much to do with your hygiene, which sounds excellent.
