Y'all indirectly set the standard for courtship so.....
And like another poster said, people, not only men are going to put in the least amount of effort to attain something.
"If she's worth it I'll go the extra mile"
But I've seen it first hand the actions listed above has gotten a nikka no play while I ate by literally doing nothing. Back when I was in college there was this fine slim athletic chocolate chick that went to my high school. She had this dude that was pursuing her for the longest. Always calling her beautiful and stuff on her IG pics, always walking her to class, using his meal card for her at the cafe. He wasn't ugly or anything (no homo) and was a legitimately good dude. Now here comes me on the other hand and I don't consider myself a bad dude, but I am the type of nikka who will put in the least effort possible to get in some draws if I can. So I've casually talked to this girl a few times, she's a friend of a friend and went to my high school, I always tease her about shyt yadda yadda I can tell she's feeling me.
So one night she ask me out the blue if I wanted to get anything to eat and she would buy. That night I didn't feel like going out because I had already made plans for another girl to come through the spot, but she said she would pick up Chinese food for carryout. She got dressed all nice under the presumption that we would be eating together in my room, but at this point the other girl had already arrived and we were watching TV on the couch. Her face just dropped to complete disappointment. She flashed a fake smile dropped off the food and left. Despite all that she was still fukking with the boy and a few weeks later I smashed
One day I asked her about the other dude basically telling her, you know he really likes you and she just said she wasn't interested and he was doing too much

.
Moral of the story. I'm not saying she was obliged to fukk with that other dude just because he gave her attention, but as a proud red-blooded heterosexual male, I'm looking at this situation like I never want to be that guy. Especially since I was able to attain everything he pined for with little to no effort. This wasn't a bum bytch either, this was beautiful college educated girl who got a degree in Petroleum Engineering. This is just my example, but I'm sure most brehs on the Coli have been on one side of a story similar to this and realize that a lot of things in the OP are simply unnecessary.
