Hi well this is pretty embarrassing but it's eating me up inside in more then one way. Well about 4 days ago my boyfriend's butt was itching he has been none stop itching it. Well we have about 2 days ago and now my vigina smells bad like fish. He is circumsized and all but we have been together for about 4 years now it smelled fishy  like this a few other times  after we had sex but I got treated and I normally get yeast infections as well after having sex with him .But I am now wondering if it only sometimes smells fishy like this because he might be cheating on me. We have had sex alot in the past 4 months with out it stinking like fish after wards. I did however get a few yeast infections in between times though. I know who I slept with and it's only him. My heart is breaking since I have suspectted him of cheating on me for a while now but I have no proof. And he makes me feel like I am just crazy or something. Does anyone else out there have a similar issue or can help me shine some light on what can be going one. Cause I am feeling like I no longer want to be with him but we have two babies together and I depend on him Solly but I will not stand for him cheating on me and will have to get it together and leave.
