No, there is no reason to suspect an STD based on blood in the feces. Rather, than an STD one would suspect a bowel disorder or hemorrhoids. The color of the blood in your stool indicates from where in the bowl the problem is. Black tarry blood suggests digestion and therefore the blood is coming from very high up along the intestinal tract (ulcer). Bright red blood suggests a bleed close to the rectum (hemorrhoids, fissure or simply a scrape from a hard stool). If the bleeding continues to the next bowel movement, seek advice from a medical professional.
std means sexually transmitted disease.
That is blood and you were cut probably by finger nails or it was too rough. There are several other option, bleeding during sexual activity can be a sign of and STD. If you are close to your period it may be menstrual blood and nothing to worry about.
possible kidney or bladder infection?
Std, Aids , blood borne disease , infected cow.
Any fluid transmitted, even spit can be an issue. So yes, menstrual blood could be dangerous if swallowed if you have HPV or any STI/STD's. Would not recommend him doing such a thing unless you both are tested.
Still a risk of STD.
