The relative health benefits (and risks) of different sexual activities

A wide range of better psychological and physiological health indices are associated specifically with penile-vaginal intercourse.

Other sexual activities have weaker, no, or (in the cases of masturbation and anal intercourse) inverse associations with health indices.

Condom use appears to impair some benefits of penile-vaginal intercourse. Only a few of the research designs allow for causal inferences.
