Our culture has a discourse of men being 'casanova's or 'player's.
As a result, a lot of women in the dating world are made overly wary and self protective of new men and their motives.
The article linked below cites research that indicates that most men are not that different to women. Even college age men in their sexual prime, indicate that they would prefer similar numbers of sex-partners and value connection and companionship in a relationship.
The 'casanova' discourse negatively affects both men and women alike.
A woman who believes it can become overly anxious about being used and avoid sex. Alternatively, she can be prone to using sex as a currency to attract a partner. In either of these stances, she may lose touch with her own emotions and attachment processes, offering sex when she feels like she 'should', rather then when she genuinely feels close enough to her partner.
Similarly, ascribing to this discourse removes men from connection with their authenticity. After all, it would not be 'manly' to reject a reasonable offer of sex would it? What would she think? What would his mates say if they found out? ...and what impression would you get if he didn't at least try to come on to you ladies?
I'm not suggesting that there aren't men out there who are only after sex. However ladies, the next time you condemn someone as a 'player', just pause... he may be as confused by, and trapped in our culturally constructed dating world as you are!
