What Can I Do To Treat A Small Red Boil Close To The Genitals?

Hi, quick question. I’ve looked up all types of stuff of what it could be. And now I’m scared. I’ve had only 1 sexual partner in a year. And just recently, say, 4 days max, I have this red dime sized spot it’s like it’s missing skin but there’s still hair there (pubic close to thigh) and it hurts, there’s also other small spots 3 similar to that one that feel sore. I’ve recently used new products and lotions, it could be that because I have sensitive skin. But I’m paranoid. I do not have insurance right now and I cannot afford the doctor. I just need reassurance or a possibility.
