Would a baalat teshuva need a get from each previous sexual relationship? In light of the idea that marriage can be contracted solely through bi'ah/public knowledge of the couple's relationship (as discussed here and here), would a woman who has had previous sexual relationships--perhaps a baalat teshuva--need a get from each one in order to be married again? What other obligations rest on her previous partners?
NOTE: If this situation is relevant to you, please consult with your Rabbi.
