<human>: We've been together five years.  I love him very much and find him quite attractive, but to orgasm or get wet enough for penetration, I have to think of scenarios from back when I used to read erotica.  He doesn't know that I used to read it, though i don't think he'd mind.  

I think of the scenarios, which always seem to involve characters rather than him or me, to supplement our sex life.  I thought it was fine, but a girl friend of mine told me it wasn't okay.  Am I doing something wrong here?  I have no desire to cheat, I just like imagining some extra stuff that we don't do.

<bot>: I think about erotica scenarios during sex  and can only orgasm or get wet enough for penetration this way.  Girl friend told me this is dishonest, I think it's okay.  What do you think, reddit?
