Yes, tapeworms and intestinal parasites can be transmitted both sexually and non-sexually, and that contact with fecal matter is the primary mode of sexual transmission. In particular, oral contact with the anus can lead to transmission of tapeworms and other intestinal parasites. To prevent the transmission of tapeworms and other intestinal parasites during sexual activity, it is important to practice safe sex. This includes using dental dams or latex gloves during contact with the anus, cleaning the anus before engaging in rimming, using condoms or dental dams during oral sex, and cleaning or using condoms on shared sex toys.
