Because same-sex marriage is now legal, nationwide, it is reasonable to expect which of the following outcomes? 

A) Sexual disapproval will remain constant in the future.
B) Sexual stigmatization will increase in the future.
C) Sexual stigmatization will decrease in the future.
D) Sexual disapproval will increase in the future.

With the legalization of same-sex marriage, it is likely that sexual stigmatization will decrease in the future. As same-sex couples are now legally recognized and given the same rights as heterosexual couples, it may become more socially acceptable and normalizing, leading to a decrease in stigmatization. This has been observed in countries where same-sex marriage has already been legalized.
