The odor began after I started having sex with my partner. I had unprotected sex before with a different guy whose spermhad no odor compare to my current partner. Could the smell come from his smelly semen mix with mine.

So you're both male?

I was going to suggest that you see a doctor, that this could be a possible yeast infection, or other vaginal infection, but when you said that his smelly semen is mixing with yours, I'm assuming, even though your semen mixing with his wouldn't be possible, that you're both male. Is that correct?
