Help, anyone have any idea what this could be?

I had PROTECTED sex with this girl but she was on her period, almost 1 week after i noticed this rash it doesnt hurt or seems to have any texture. feels a little sensitive when i touch. Got a blood test tomorrow but im freaking out, help anyone?

have you had it checked yet?
it looks a little bit like a reaction to something

It is more likely linked to you shaving the area - to be sure of what is going on you would need to see a Dermatologist

I agree with this comment, it is likely due to the irritation from shaving. Stop shaving and this will cease to occur.
