rash!

Hey guys! So yesterday I get the opportunity to sleep next to my boyfriend m with whom I have done jut about everything but have sex and I woke up with an itchy rash on my pubic area. Then as the day when on my entire upper body broke out into extremely itchy blotchy rashes. This morning I woke up with it on my face too. The scary part is my boyfriend is experiencing the exact same symptoms. What do you think this could be???
