With partner for about 2 years. Started having issues with yeast infections for. About a month later, I tested positive for trichimoniasis and was treated. He was too. Within three months of that, I tested positive for chlamydia. We were both treated. I did not stray outside of the relationship. He swears that he did not stray outside of the relationship. Not sure when either of us would have had the time or stamina. We were very vigorous and experimental (unprotected vaginal, anal, oral, vibrator usage, and a set of ben-wa balls that I used for a time). He claims I was his first sexual partner. (unknown to me before). He was not mine, but I was in a supposedly committed relationship 2 years before)
How could we have contracted the chlamydia? This has caused a lot of stress in the relationship. He thinks I am lying when I tell him that I have been with no one else but him since we met. (Didn't want to be with anyone else, just him)
Prefer a physician answer, please.
