Although there are more than 30 STI‘s which may be sexually transmitted, you have tested for the most common ones. At this point I see no reason for continuing concern or testing for the STI as you have listed. On the other hand, for any asymptomatic person who has multiple sexual partners, who is entering new relationships, or who has partners who may have multiple partners, we do recommend an annual sexual health check up as a good idea (and perhaps more often if you think your risks are particularly high).  Such testing should focus on Gonorrhea, chlamydia and for women trichamonas.  Most people would include testing for HIV and Syphilis as well even though these infections are far less common.  We specifically recommend against routine blood tests for herpes (the tests are not good enough and because of false positive results just confuse things).
