It depends on what it means by "occasionally" if it means whenever your partner has an STI then its that but due to its vague meaning I would say its using condoms consistently.
Answer:
by using condoms consistently during sex
Explanation:
Condoms are at the heart of a combined HIV prevention approach; They are also a cost-effective tool as they work to prevent other sexually transmitted infections and prevent unwanted pregnancy.
In 2015, an estimated 1.9 million adults (15 years and older) were infected with HIV - the vast majority through sexual transmission - and approximately 357 million people acquired chlamydia, gonorrhea, syphilis or trichomoniasis. Condoms effectively prevent all these conditions.
For this reason, we can say that a safe way to prevent sexually transmitted diseases is through consistent condom use during sex.
