My problem is that the higher inner area of my thighs are getting sweaty and smelly. This is not due to some phisical activity. I regulary take baths. I think this situation is not related to the underwear or clothes i wear, since it appears no matter what kind of underwear/clothes i wear at the moment.
You don't say whether you are a man or woman. Women can get vaginal/genital odors that can be a sign of infection, especially with bacterial vaginosis or trichomonas. No STD causes actual skin odor. Often it's a sign of bacterial overgrowth, which is expecially common in overweight people. I don't know of any solution other than what you're already doing--wash often, loose-fitting underwear, etc.
