In the space of a year ,four times this has happened, after sex with my boyfriend my vagina smelled like condom.we do not use condoms so I assumed he had cheated on me.I figured no matter how well he washed his penis ,after he next ejaculated ,the condom smell would come out (into me). I was scared and thought oh no! Disbelief. I have told him each time what I smelled but he denies it and gets upset that I don't trust him.I say I do(did?) trust him its just that I smelled condom!! I know what people can be capable of e.g. lying cheating. So it's hard to just believe him.. I feel like he's been unfaithful but I can't find out or know for sure.:(.. It is time consuming and stressful trying to believe him but feeling confused and hurt that he mite have... any advice ?thanks..
