I just looked up the legal definition of “sex act” for clarification.
This is from Cornell (www.cornell.law.edu):
sexual act
(1) Sexual act .— The term “sexual act” means— (A) the penetration, however slight, of the penis into the vulva or anus or mouth; (B) contact between the mouth and the penis, vulva, scrotum, or anus; or© the penetration, however slight, of the vulva or penis or anus of another by any part of the body or any object, with an intent to abuse, humiliate, harass, or degrade any person or to arouse or gratify the sexual desire of any person.
@seawulf575 “having sex” is not the only “sex act” but the descriptions you gave about playful touching weren’t what I would consider a sex act, which was why I looked at the legal definition. Apparently, context matters, in addition to the type of touching/exchange.
