Three on a Match (1998)

Sinopsis

Lesbian couple Beth and Claire have been together for a year, and it's high time (at least in Beth's mind, if not in Claire's) that they have a baby. After ruling out adoption or artificial insemination, Beth starts methodically seeking out a proper man to be the father. Enter David, who seems to fit the bill to a T; trouble is, he immediately falls in love with … Claire.
