Fishy smell during and after sex

[B_Rada]

Hi, my girlfriend and I have been having sex and ever since the first time we had sex (she hasn't in over a year before me) she has a fishy smell. We are trying to figure out why and she has went to a woman's hospital in Korea yesterday and they told her there was nothing wrong with her although it could be because she hasn't has sex so long. But she also raised the concern that it maybe my seman. I was reading a little but I don't know how much I trust what I have been reading. Could it be my seman with her fluids mix that is making this smell and if so, how do we fix this. (or if it is me, how do I fix this. I am on some meds for pain, hydromorphin and percet for horrible neck pain) She wants me to goto the doctor before she comes back home but I would really like to know what it is and how we can fix this. I love her dearly and I want her to be comfortable with having sex without the smell. The smell comes only when we start having sex. She does get really wet and I do *** a lot when I do inside her. Is there something I should stop or should start eating or drinking? Any help or any questions anyone would like to ask to help us figure this out would be great. Thank you.

Look up BV.  You both should have a run of antibiotics at the same time if that is what it is.  She should get swabbed for it specifically at the doctor and they can see if that is the problem.

It sounds like you both have a bacteria, which causes vaginosis.  The other most common condition is yeast, but it has more of a sour smell rather than fish.
