How long sex lasts

The longer the duration of sex, the higher the risk of infection.

This is easy to understand. The longer mucous membranes are in contact with body fluids that contain HIV, the higher the risk that HIV may get though.

Sex lasting for longer can also increase the chance of tissue damage.

However, other factors are more important.

Quick sex without a condom is a much higher risk than long slow sex using a condom.
