It is very very unlikely that you could get HIV this way. We are not seeing men get HIV from receiving oral sex. If you like, you can get an HIV test for reassurance. I do not know specifically about which tests are available in India. In BC, we would recommend an HIV antibody test 3 weeks to 3 months after the sex.
It would be a good idea to get a test for syphilis, gonorrhea and chlamydia after having unprotected oral sex. These are much more likely to be transmitted to you through oral sex, and they can have no noticeable symptoms.
Let us know if that helps answer your question,
