Whitish/yellowish discharge is totally normal. A strong odor, on the other hand, is not. Ally_cat could be right. Maybe it's BV (Bacterial Vaginosis). It would cause a strong odor, usually "fishy" smelling. It's easy to diagnose and treat, though, and it's not necessarily caused by intercourse, so don't be embarassed. If you think that's what it is, ask your doctor...I'm sure he deals with BV all the time. It's fairly common. Good luck!
i have almost the same thing as you , i went for and STD and HIV test because i had really horrible smelling white sticky discharge , literally all the time , i had no itchiness or pain or anything but its horrible and embarassing but they found nothing wrong with me, most STD tests dont sest your Bacterial vaginosis wich isn't an STD its caused my a natural increase of bacteria in your vagina, this is what i had , its treatable with antibiotics , but sometimes comes back maybe you have that?? hope this helps x
