I will tell you what men have told me their reactions are when this has happened to them. If you have been unfaithful, had unprotected penetrative sex with another man despite your 'patching things up' I can assure you there is one image that will never leave your boyfriend's mind. And that is of that other man penetrating you, having sex with you and leaving his fluid inside you. And that image is on an endless mental loop so every time you are intimate he is seeing what that guy did with you. Flat out period no kidding. So regardless of how you may try to convince him you are not riddled with disease he is at DIS-EASE with what happened. I would be surprised if your relationship lasts much longer as this is a man who cannot feel connected to you as a man wants to with a woman and that is crucial to a relationship.

Sorry to have to be so honest but I want you to know how men's minds work in these situations.
