Ive only had oral sex because im scared to actually have vaginal sex. Since im still experiencing a burning sensation even though all my tests keep coming back cleared

I have been sexually active since after getting treated. So the entire time I’ve dealt with these symptoms. My partner is fine and hasn’t had any changes in his genitalia or anything like that. Having sex often increases my symptoms, but in terms of it being spreadable.. I don’t think that it is.
