I have a small bump on my scrotum. it looks like ingrown hair or pimple? i'm worry that it's std, but i'm a virgin please help. is it normal?

Nice observation...: You are right with what you observed and described because this bump most likely represents a hyperactive sebaceous gland of hair follicle, which is harmless & needs no active care unless having recurrent infection or other bothers. Of course, without a direct look at and feel on it, it is hard to offer perfect diagnosis. More? Seek evaluation.counseling timely. Best wish to health...
