If your goal is to get laid, of course it’s easier if you are a girl. Dating is a whole other story, because men and women are completely different.
As men, what we want from a woman is their body, so to get that, we need to give them is our attention. This is where things like flowers to show to we’re thinking about them, spending time with them on the phone, etc. all come in. If you’re not giving them your attention, you’re not separating yourself from any other man.
As women, what they want from a man is their attention, so the way they get that is with their bodies. Now they can’t just give it all up because then they’ll be nothing left, so they have to do it one piece at a time. It starts with makeup and a nice outfit to accentuate their curves. Eventually it will move on to touching, revealing selfies, etc. The better job you do, the more access you get. Their bodies their reward to you, and in turn is what separate themselves to you.
Dating and all of its dynamics make perfect sense when you think of it through the lenses of evolution. Men are bigger and stronger, so we’re the providers. Women bear children, so they’re the nurturers.
Men get to spread their seed, so we want to sleep with as many girls as we can. Women have to carry that seed for 9 months, and are then left with the child, so they are extremely selective.
When men decide to get selective, being the providers, we supply ourselves with what we need to survive, so we look for physical traits in the woman which signify health, increasing the chances of healthy offspring.
Women care about that too, but for them survival is far more dependent on picking a man that can provide and protect her and her offspring, not to mention one that will stick around to do that.
So basically, it’s just biology combined with the realities of life in earth. Moral of the story is that if you think women have it easier it’s probably because you haven’t thought about their point of view very well.
