I left out a crucial point with regard to the cheating question.

I always told my fiance within 24 hours of anything physical happening. If I was out of town, I would call him the next day. If I was in town, I would tell him the first time I saw him. So he didn't have to worry about whether I was hiding physical cheating.

I did hide email/text/picture communication, however, so that part is probably about the same as for your situation, and he trusts me not to do that.
