if you think about the person you are with no just because she doen't want you for the night doesn't mean you can't satify yourself. a hand is a terrible thing to waste. it knows what i like doesn't bitch at me and always pleasures me right.
there isn't another person involved so i don't see a problem with it. Actually I think it might help to keep guys from not cheating. Men have needs that that the women may not be able to provide at the moment.
It could be, if you use the hand that you don't normally use. Could lead to a serious self thumb wrestling match to decide who gets some lol.....No, it's not cheating.
If you are the one masturbating yourself, How can that even be considered cheating?
