Suggest Tests To Diagnose Gonorrhea And Syphilis
Yes you need to test for some STI.
Detailed Answer:
Hello! I have been through your question.
Related your concern and based on your history, having protected sex and oral sex without condom (mentioned in the XXXXXXX free question) I think you should test to exclude some STI like chlamydia, gonorrhea ,syphilis, HPV (but very rare HSV and trichomoniasis).
Furthermore you should know that exist very low possibility to get HIV infection
from unprotected oral sex, so in your case it is not necessary to test for HIV.
Usually some STI may be transmitted by oral sex and can be spread to a sex partner even when the infected partner has no signs or symptoms.
I hope my answer helps you.
Feel free to ask me further.
Regards.
