Blood on the condom may be due to your partner's blood. commonly due to mucosal tears or laceration. If you're observing it inside the condom then possibility of blood from you. Don't apply on penis any irritants it may aggravate the problem. Use antibiotics if you're having blood or pus from urethra or in urine. Still have doubt you get it done urethral secretions culture and sensitivity. Please consult your physician, he will examine and treat you accordingly. Take care. </s>
