Can one have sex as a woman during shiva? or how long after shiva can one have sex?
Hamakom yinachem eschem b’toch shar aveilei tzion v’yerushalayim.
Regarding your question, the laws regarding intimacy between the married couple only apply during shiva and not afterwards. Aside from actual intimacy, the couple should also abstain from kissing, hugging or sleeping in the same bed. Everything else is permitted.
Shulchan Aruch 393-1.
