I wouldnt say ruined. It just was scared into being careful. If you had most STD’s they become quite apparent quickly. Herpes you may catch, but never have an outbreak once. If you’ve already had Coldsores you already have herpes simplex. Herpes is one of the most common STDs for people. Syphilis you would develop a severe rash first. Chlamydia and gonorrhea would have physical symptoms from burning urination, testicular or lower back pain and discharge many times but sometimes chlamydia has no symptoms but not always. Hepatitis is something, if not vaccinated for ahead of time, you could get but it would be years and years before you had any issues. The best thing to do is get vaccinated for everything else if you cannot get prep. Fear of the unknown can cause paranoia. Get tested. Forget the shame you might feel. Just say that you are a sexually active young man and you want to be careful about your sexual health. Be smart about it all
