Sexual repertoire: Latent class analysis loadings

	Latent class
Behavior	1	2	3	4
Adolescents (ages 14–17)

Anal intercourse	0.000	0.000	0.540	0.037

Adults (ages 18–49)
Masturbated alone	0.561	0.741	0.961	0.642
Masturbated with partner	0.000	0.463	0.866	0.213
Gave oral sex	0.000	0.305	0.950	0.846
Received oral sex	0.007	0.243	0.981	0.877

LCA loadings are the conditional probability that someone in a particular class would respond “yes” (at least one in the last year) to a certain item. The items with higher loadings for a specific class are considered to be part of that Class. For example, the probability that someone in Class 1 indicated having engaged in solo masturbation is 0.561

In other words, 56% of the adults in Class 1 masturbated alone in the prior year

Bolded entries reflect the sexual behaviors that characterize each class
