Well, you would have to define "virgin" in order for us to answer? While you usually cannot get an STD without having intercourse, it is possible that if you are performing oral sex on your partner or they are performing oral sex on you that either of you, if previously infected, could spread gonnhorea, clamydia, or syphillis. If having oral sex still keeps you in the category of being a virgin because you didn't have anal or vaginal intercourse, then the answer is "yes, you can be a virgin and get an STD."
