Does anal sex have any effects for later on if not protective but partner is clean?

Meaning of clean?: If by clean you mean no sign of infection, you may still be putting yourself at risk if you're not using any protection. A person can be infected with hiv, hpv, herpes, and other stds with no outward signs. Why risk getting an infection that may be life-long or life-threatening? Speak with your partner about using condoms. Maybe you can make it easier by making them part of sex play.
