Hi, and thanks for your question
This can definitely be normal. Some people have bigger more palpable (able to be felt) lymph nodes very close to the surface of the body, especially if a person is on the thinner side. Others are naturally smaller and a bit deeper down and less easy to feel. The fact that they are not causing you any pain is a good thing.
Of course we also do recommend regular testing for STIs including chlamydia, gonorrhea, syphilis and HIV for all sexually active individuals regardless of whether there may be symptoms or not as many STIs don’t have any symptoms at all.
Have a look at our Clinic Finder to locate a clinic near you for testing
