I've already explained to you in great detail, including giving statistics and a visual example as to why that discrepancy exists. What exactly do you not understand? The following is pretty much exactly what I've already said - but with citations to research indicating that yes, this is the situation. You can be mad at the culture if you want to, but it's stupid to lay this only at the feet of women. I agree that it would be better for everyone if we ditched these gender norms and social stereotypes, but you've already indicated that you're not willing to do that in other contexts so that you can maintain your masculinity, so I guess you've got a problem then because you can't have it both ways.

"While assertive communication from women is generally accepted in school and work environments, this type of communication can be perceived negatively in dating and social situations. Women might still be expected to play a more submissive role in romantic relationships. For example, researchers report that by society's standards women should not be the initiators of dates (Smiler & Kubotera, 2010), verbal contact after dates, or sexual encounters by society's standards. The societal standard reinforcing these rules for women is "be desirable, not desiring." These gender differences are also prevalent in dating. For instance, when a woman initiates a date, the sexual expectation from the man increases.
When women express assertive communication by initiating a date, a violation of expected behavior according to social norms is likely to occur. Gender-based stereotypes seem to have a greater impact on romantic situations. They could be preventing women from taking on assertive roles in dating, specifically in date initiation, because they are not expected to be assertive in that situation. Women who are taking initiative might affect their dating prospects because their behaviors are seen negatively.
Stereotypes in romantic situations call for women to be passive and feminine and for men to be assertive and masculine. Muelenhard and McCoy discuss how double standards impact how women communicate about sex. The rules and stereotypes placed on women influence how they are perceived. The main focus for this study is date initiation, which is generally not an acceptable behavior for women."
