I’ve been seeing this girl for a few months now and been on many dates. A few weeks ago we were getting into it but she had stopped me to tell me that her ex gave her herpes downstairs when he was giving her oral, she was not aware that he had it she went to the dr and said herpes, she said she hasn’t had an outbreak for 3-4 years. How can I prevent from getting it and make it the safest way possible?
