Female, 34. Blood specks only in seminal discharge after intercourse. Normal pap smear. Causes? Is it that my husband could have blood in semen?

Hard to say/depends, It's hard to say what this is without more evidence of a pattern. It appears non-specific and might just be from physical contact during intercourse. If there is more evidence of blood like blood during urination, then a physical exam with lab work up is warranted. Otherwise it shouldn't be anything to worry about, especially in light of the normal Pap smear. .
