Men are often accused of lying to women in order to obtain casual sex. An example of this would be a man saying he is looking for a serious LTR, when he really only wants casual sex.

Once in a casual sexual relationship, men will often use deception and plausible deniability to continue to sleep with a woman. This is especially true if he does not use protection. Assume a man and woman have been having an ongoing casual relationship for a few months. When the woman asks if he is currently sleeping with other woman (to protect her own sexual health), the man may answer “no, only you,” when, in reality, he had a one night stand a week prior. While his response may not be a lie, it is deceptive because, had the woman known the truth, she would not sleep with him until he was tested.

Using deception is just as harmful as lying. Men should be straightforward and honest with women they are sleeping with, even if such honesty may lead to a casual relationship ending.

Caveat: Obviously not ALL men rely on deception. Yes, there are some men who offer up any information that may cause a woman to make a decision that is not in his (the man’s) interests—or, in other words, some men are honest to a fault even if it means the woman will no longer sleep with him. Nonetheless, based on experience (both my own and others’ that I am aware of), deception is not a rare occurrence.
