Are Christians not permitted to have sex with wife when she's on her period?

Acts 15:29 and 21:25 carry over four requirements from the old testament to apply to gentile Christians - one of which is abstaining from sexual immorality. In Leviticus 20:18, it makes a big deal about having sex with a woman while she's on her period. > If a man lies with a woman during her menstrual period and uncovers her nakedness, he has made naked her fountain, and she has uncovered the fountain of her blood. Both of them shall be cut off from among their people. (ESV) However, Leviticus 15:24 makes it sound more like a ceremonial issue than a sexual immorality issue (which in that case may be a requirement which has passed away under the new covenant). > And if any man lies with her and her menstrual impurity comes upon him, he shall be unclean seven days, and every bed on which he lies shall be unclean (ESV) So the question is, does the Bible prohibit sex during menstruation between a man and his wife?
