Children of lesbian mothers are 75% more likely, and children of homosexual fathers are 3 times more likely, to be currently in a same-sex romantic relationship.

The same holds true with the number of sexual partners.

Both males and females who were raised by both lesbian mothers and homosexual fathers have more opposite-sex (heterosexual) partners than children of married biological parents (daughters of homosexual fathers had twice as many). But the differences in homosexual conduct are even greater.
