What would you consider as cheating, or unacceptable in a relationship?

Last night I went out with a guy, He's mainly my brothers friend, but I suppose he is my friend too.

We were driving around in his car and he taught me how to change gear by putting my hand on it and his hand on top of mine. We talk sexually towards each other a lot. Just friendly banter really. I was told by someone that he cheated as he touched me sensually? And that maybe he is emotionally cheating?



What do you class as the first instance of cheating on someone?



Thanks, xWhat would you consider as cheating, or unacceptable in a relationship?
Touching can be considered cheating if it were your leg, breast, or butt. But this is your hand and he was teaching you how to change gears. Not cheating.
