I had sex a few days ago with a codom on. Now I have red flacky ichy spots on my penis, scrotum is very red and flacky, and also a red rash on my inner thighs. Please help is it an std?

Could be... have you gone to a doctor and gotten tested yet? That's the only way you can know for certain, or get treatment if you have got something..

I get pinkish rash things if I wear a latex bandaid so maybe you just have an allergy to latex condoms...
