question: Hi doctor, I am a 20 years old female, who weighs 224 lbs, and I am 5.4 feet tall. I have what looks like a pimple on my crotch. It keeps coming back in the same spot and produces white pus and a lot of blood. Is there a chance I have an STI? I have had it since before I became sexually active. I always use a condom. I have attached a photo of the pimple.
