Im DEVASTATED. Told I have genital after 11 years of celibacy. Ive just met a man. How do u tell him?

I have not been with a man in 11 years. My ex cheated on me through most of our relationship, and I'm a pretty smart lady, but it never even crossed my mind that the "one" little sore that I got, at the most 2 times a year, could be an STD!! I have FINALLY met a great guy who I was considering becoming intimate with, so I went to the doctor to have a tiny little, but potentially embarring, skin tag removed from my inner thigh. I've had the thing for like two years, and never really cared that it was there till now. I asked if it could be something ped to me by my cheating ex, and she said no, but said since she was doing blood work for anemia anyway, she'd order a test for what I now know was for the Virus. My knees literally almost buckled when she called me to say the test was positive. Im profoundly shocked and saddened about this! And." HOW THE HELL CAN I TELL NOT JUST THIS MAN, BUT ANY POTENTIAL UAL PARTNER, THAT I HAVE AN STD! I just can't do it. I mean, I KNOW that I have to before I ever have with anyone again, but right now, I think Im just not going to have at all. WOW!! Is this really happening?
