Ejecting from an approach, or even from a date, is easy, if you decide you don't like the girl. But ejecting from sex is tougher, especially if you are a nice person who doesn't like to hurt people for no reason.
Why would you want to eject from sex? Well, I once got this 28-year-old Polish girl naked who looked like a 9, and when I saw her vagina it looked like a scale-covered snake. It was utterly fucking disgusting, and yet I went through with the whole thing (no condom either lol), partly because the rest of her was super-hot and I wanted her anyway, and partly because I didn't know what to say to her if I went ahead and started putting my clothes back on. So though in the end I did have sex with her, I can easily imagine situations in the future in which I would categorically not want to go through with it (e.g. with some of those huge-titted plump girls I find from time to time; many of them are quite tight down there, but I can easily imagine running into a disgusting one at some point that turns me completely off when naked).
So my solution is simple. The moment you realize you don't want to do it, you tense up, and withdraw from her on the bed a little, and then you say, "You know what... I can't do this". And then you proceed to explain to her that you actually have a girlfriend that you love very much, and you thought you could cheat on her because you found the girl in your bed hot (thus giving her a strong compliment to sweeten the deal), but now you realize you can't because you keep thinking of your girlfriend and of how you are being deceptive to her, or some shit.
And that's it: get dressed, and off you go, with no one really hurt too much.
I am guessing this could also work to save you face if you are having erectile issues, though I don't know from experience.
