Hi there. From your symptoms, it appears you have a mild UTI. This can have been due to a frictional issue not necessarily an STD
. Having said that chlamydial infections do often give rise to UTI. However, this is not as common with oral sex
as with other forms. Still, it is best you consult with a dermatologist
or STD specialist nearest you on the ground & do the relevant urine/lab tests the good doctor would advice. Accordingly, you will have to take the relevant antibiotics et al. In the interim, you may try to consume lots of water/liquids to flush out the infection together with a urinary alkaliniser that any pharmacist may suggest over the counter & may be taken as an effervescent powder in a glass of water. Cheers & Good luck!
