You are young and whatever you want to try is fine.
But your average college educated woman doesn’t get married until she is 30. Marriage won’t be a force in most relationships for years to come. You all have a lot of milestones to get through before marriage starts sounding realistic to people. Relationships at this stage are about learning, exploration and companionship, not about finding a life mate. And of course, sex is a big part of that for most people.
The thing that is going to hamper your dating the most is not not drinking or not playing sports, which quickly will become less relevant. It is your clear tendency to overthink and over analyze.
The creed that you just wrote shows you have out a lot of thought and expectations in to this theoretical relationship. What is missing? The girl. Basically you’ve already written the story in your head, and and you just need the right girl to fill in. The problem is that nobody wants to be in a relationship that had already been written. Nobody wants to feel cast in a role. Whatever reality brings is not going to resemble your fantasy at all, and you need to be ready to embrace that. Any woman you date is a person with her own ideas and desires, not a prop in your plan.
Relax, take life as it comes, experience as much as life throws at you, stretch your comfort zones as wide as they will go, study, travel, make the occasional bad decisions. Embrace life so thoroughly that you don’t have time to think about yourself all day. It will come together eventually.
