According to studies, the guy does not like to be refused when asked to make love. Well, I am a guy and I agree with this article.
So next time, just say yes for better relationships. (You can email me if it doesn’t work to: bed@bedzine.com)

For him, when you refused his (brave, risky) offer to make love, you refused his manhood. Translation: You refused him as a man. He feels bad about himself as a man, refused by his girlfriend, fiancée, or wife, rejected by the woman he loves, his manhood rejected by the woman he loves, his manhood refused and rejected.
