Lot's virgin daughters had husbands?

According to Genesis 19:7-8 (NASB), Lot offered his virgin daughters to the men of the city so they would not sodomize the visiting angels: > 7 “Please, my brothers, do not act wickedly. 8 Now behold, I have two > daughters who have not had relations with man; please let me bring > them out to you, and do to them whatever you like..." However, Genesis 19:14 (NASB) implies they either had husbands or were pledged to husbands: > "Lot went out and spoke to his sons-in-law, who were to marry his > daughters..." **Am I missing something?**
