Is it normal to be tired during sex?

I have a partner and a lover. Yes, I know it is wrong. I am not here for advice on that.
When I have sex with my partner I have loads of fun, and can go on for hours (even though I never cum); with my lover, I get tired easily and want him to do the driving. I also get sore really quickly and want stop.
What is wrong?
I am also much more sexually attracted to my lover as well. This is fucking weird, I hate when my head messes me up like this. So what do you guys think, normal or not?

    You need to end it with one of them. Maybe you are tired since you are screwing to chicks.

    Just not enough of you to go around. You may have to pick.
