Red flag?

Now, that I think about it. His story doesn't fit in the right time frames. I remember he talked about him being a virgin still after the date he told me he stopped sexing her.

IMO, there should be no secrets between lovers, partners. Trust is what builds a relationship and lies are what destroy it-as exampled here.

If he cares, he would make it his first priority to clear any doubts about his integrity and faithfulness. As Gigabitch said, Lying is ALWAYS a red flag.
