Hi, I am a college student and worried if I have an STD. There are smelly red bumps on my scrotum and thigh that I noticed about 3 days ago. They haven't itched very badly, but I feel like they are starting to. I have read that the strong smell could be from a yeast infection. Is it possible I have herpes or genital warts ? The last time I had sex was almost exactly two months ago. Any feedback would be greatly appreciated. Thanks
