Dam Betulim questions

25 September, 2003


I have several questions about dam betulim:

1) I have heard that the rules for seeing blood of dam betulim are stricter than those for stains (meaning, seeing blood after initial intercourse could be a problem even on colored sheets or paper tissue). Is this true?

2) Can you be required to keep dam betulim more than once, say, if you see blood after first and second intercourse? What about first and third, but not second?

3) I saw that if you see blood after partial penetration, this is dam betulim. The next time such a couple would have sex, and achieve full penetration (for the first time), would she be a nidda again, even if she did not see blood?


1) If there was full penetration – even without any bleeding – the couple become forbidden to each other, and she must count days and go to the mikveh before resuming relations, as after any niddah period.

2) As long as bleeding continues to occur with each intercourse, it is considered dam betulim. The couple are required to separate each time, and the wife counts days and immerses. If on one occasion there is no bleeding after intercourse, then dam betulim is finished. If, on a subsequent occasion, she again bleeds after intercourse, it is not considered dam betulim. (It might be halachically more severe, so a question should be asked.)

3) If the first intercourse was partial penetration with bleeding, it is considered dam betulim. Therefore, if the second intercourse was full penetration WITHOUT any bleeding, the second intercourse does NOT make her niddah again.  She is finished with the laws of dam betulim.


Please see the article on dam betulim for more information and explanations.
