Is Candida a sexually transmitted infection/condition? Or does it come on naturally even if the person is not sexually active? I'm in doubt...I think my now exboyfriend gave me Candida. While I was with my ex, I had 4 bouts with Candida (we always had sex without a condom). Each time I went to my gyn. he gave me a prescription for an antibiotic as well as a prescription for my ex, so we would both be clean. The doctor also recommended I change my soap as I might be allergic to it and to not wear any tight fitting clothing. I obeyed my doctor but never feel quite rid of Candida, there was always some lingering twinges of swelling or itchiness or burning, infact, I remember one time, just 5 minutes after having sex with my ex, my vagina swelled up like a balloon and the next day the burning and itching began. Well, now that I am no longer with my ex (9 months now) I no longer have any effects or symptoms of Candida and I have even gone back to using my old brand of soap....and I now have started a sexual relationship with my new boyfriend and I feel A-OK, perfect infact. Completely clean without any signs of Candida. Any ideas out there? I still think my exboyfriend gave me Candida...but my research tells me it's not a sexually transmitted disease. But I think I'm living proof that it is. Another thought...could it be that I am possibly allergic to the anti-spermicide that is used on most condoms?....Meaning, my ex was having sexual relations with someone else...and then coming to me for sex and there was possibly still a residue left on his penis that infected me? All is possible. I know folks, thank God that I am free of the jerk...but my mind wonders sometimes about this, I mean, it is my health. Thanks readers!
