The curious part to me was the possibility that masturbation reduces the chance of STI. How does that work?

In the context of masturbation following intercourse, it probably has a flushing effect (which presumably would reduce the risk of infection reaching the testes and possibly causing infertility--post-coital urination supposedly has similar benefits).

I always wondered why I had to pee afterwards.
