sentences:  The benefits of sex acts are various, and if an individual is concerned about sexual infections or pregnancy, non-penetrative sex acts (which carry a significantly smaller risk than penetrative sex) can be sufficient in preventing the risks, and offer a wide variety of options to choose from.There is a sociocultural viewpoint that because non-penetrative sex usually does not involve a direct exchange of semen or vaginal fluids, and because at no point (in exclusively non-penetrative sex acts) does anything penetrate the vulva, vagina or anus, these acts are risk free.Although the risks associated with non-penetrative sex acts are significantly less than those associated with penetrative sex, there are still risks that can occur.
