You three guys - College, Helpme, and IBM - need to stop this baseless theorizing and get out there to get some experience under your belts. This banter, while amusing, is total nonsense.
College - man, please go out and give it a try. You present things as if you are an authority, which you're clearly not. I don't mean that in an insulting way. You spend hours, months, probably years wasting time thinking about possible outcomes. You are obsessive about it. Unless you want to marry your screwdriver (sorry, couldn't resist), stop trying to justify things to yourself through the use of formulae and statistics. To put it bluntly (and I mean it in a helping way), a lot of conclusions that you draw about girls are mock-worthy nerdy bullshit. You're a newbie with this girl thing, and there's not a damn thing wrong with that. We all have been at some point. However, you need to stop acting like you've got things figured out and instead go out and learn.
Helpme - sometimes you seem rational, sometimes downright insane. You've given some good advice but I doubt you've applied it in your own life. You owe it to yourself to do something about it. If you don't try, then you don't deserve.
IBM - well, what can I tell you? I doubt anything has soaked into your head. Your statement "The only thing on relationships, marriage etc etc that matters is pleasure" is so misguided that I think there may be no hope for you. Certainly, pleasure is a necessary part of any serious relationship...but if you think that's all it's about, then you're going to be sorely disappointed when you continue to get nowhere. Serious relationships are also about support, guidance, love, respect, and honor. Indeed, if a relationship proceeds to marriage, then your mate becomes family. If what you said is truly your attitude, then I can see why no girl considers you dating material.
