Been having unprotected sexual activities?
Then you have a high risk of any number of STIs, and sugar, that's a choice you made, and the only person who could have done anything about that was you.
Whether you have an undiagnosed UTI, yeast infection or a more serious STI, you need to go to your doctor/GYN or to a health clinic. That's nonnegotiable, because neither we nor you can self-diagnose or treat any kind of genital infection.
So, to be blunt, you got yourself to wherever you were taking these risks, so you can get yourself to a health clinic just as easily, and that's what you need to do. being able to do that, love, is part of being ready to be sexually active.
