I have small black painless spots developing around my scrotum, what might be the problem and how should i fix it?

Blackheads...: Likely, what you described are the common entity of skin disorders called blackheads resulting from dried plugged-up sebaceous glands, which are prone to develop in some people usually on forehead, back, & external genitalia, and need no active treatment due to their innocuousness. Of course, a direct look at them is essential for right diagnosis. More? Seek evaluation and counseling; don't worry.
