I Was Raped In March Of 2014. I Had All

I was raped in March of 2014. I had all the STD tests run in April 2014 and repeated in October 2014. Everything was clear. Sometime during the fall of 2014, I broke out with a rash in my pubic area, groin and legs. It has now spread to other places. Today, I was diagnosed with molluscum contagiosum. I have not had sex since the attack. I am a life-long, severe Type 1 diabetic and have a very compromised immune system. Do you think the MC virus is from the rape that was over a year ago or could it be a consequence of my immune system. I don't guess it really matters. I just hope that it wasn't sexually transmitted. I don't want to be reminded of that day.
