Husband's sperm

Every time I have sex, his sperm is irritating my vagina and I have worse symptoms of itchiness and bad odor. I have some sort of fungal infection. I suspect I got it from my husband as I have it since we are married (6 years) When I went to the obgyn for checkup he thought it was yeast infection by mere listening to my complain. He never tested it in lab. Back then I had no rash but now I have slight rash, and my vagina looks red and irritated. I refuse to do sex until I am healed and my husband as well to be free of whatever is it can be transmitted to me.
My husband used to have fungal rash in his genitals and his feet. He forgot about treating it before we were married, and forgot about avoiding sex until it was healed. He used some conventional cream (Loprox Gel) on his feet and his genitals and the fungal infection was gone. (6 years ago)
but now he has fungal infection in his feet again. The bad odor from his feet is similiar to the bad odor in my vagina.
I need help, this is realy irritating me! I wonder if I will use achidophilus pills or tea tree oil or coconut oil, what if HIS sperm is irritating me? Tweet
