I'm a 23 year old straight male, I saw a video something called urethral sounding, and tried it out of curiosity just to know what it is with a small tube, it was really painful ,and now at end of urinating there is blood, i'm scared and don't want anyone to know about this, I don't have any pain or anything, it's been a day I just want to know, will it be ok if I just let it be and everything will be automatically go normal, or what should I do, the blood is only after urinating, and not out of control, what should I do.
