technicaly I haven\'t cheated because i never had mens raia (guilty concience) but some people could call it cheating, once when I was supposed to be at my gf\'s house, my cousin came to visit me, and she brought along her friend, and her friend kept on trying to suduce me, but I fought her off....for the most part, hehehe..... and there was only some heavy petting that happend, so it depends on who you talk to, on whether it was cheating or not.
but the worst thing i have done in that area was I almost broke up a marriage. a girl really liked me and was going to divorce her hubby for me, but i told her no. (she looked like penelope cruze)
