The only way to know one's sexual health is to be tested. If you are concerned about it, I encourage you to do so.I encourage all sexually active people to be tested regularly for all STIs, including HIV , it may be every 3-4 months, bi-annually or annually, depending on an individual.Did you have a word with your family doctor regarding your symptoms if not please take an appointment and do so as he is the right person to address your concerns.
