There are four levels of relationships in a human society, and no other can exist besides those four: a) Total strangers. b) Known persons (neighbors, colleagues etc) c) Friends/enemies (higher in the passion scale; they care for/hate you more than b) and d) Flirt mates/lovers/spouses (sex or desire for sex is involved)
The problem with this scale is that you can only move upwards (a through d) and never downwards. For instance a neighbor can never become a perfect stranger no matter how many decades pass without seeing him and a former wife will for ever be "your ex" no matter how much friends/enemies you may have become after the divorce.
According to this scale when sex/desire is involved, every relationship is upgraded to d immediately. For example, if two perfect strangers have an ONS and then - two years later - the man sees the girl on the street, he will tell his friends: "Guys! Look over there! A girl I once screwed" and not "Oh! There's a perfect stranger" or "A good friend of mine" because the obvious question ensues: "Where did you met her?" and he has to reply "We just had sex once" (class d). In the same way, if two friends have sex they are not friends any more. They are class d.
When between two persons things can proceed up to class d they can never (ever) remain to classes a/b/c (unless at least one of them is so ugly/unattractive). And in the natural course of things, between a man and a woman (both fairly attractive) things can escalate up to d. Golden rule: Friends don't have sex/desire (or think of them). If they do (even just naughty thoughts) they are friends no more.
I can't imagine two guys drinking beer in a bowling center (or two girls talking about lipsticks) to think nude of each other: "Hey, dude! Your ass is hot! I'll lick it!". That's why two girls may change swimsuits in the same locker room without feeling attraction from their nudity. For the same reason (nude) players of a sports team don't (normally) fuck among them in the changing/hotel rooms. They are not attracted to each other. They are friends/colleagues. They only arrive to classes b/c.
But imagine two opposite-sex friends to change/sleep in the same room! An awkward situation! Because they can proceed to class d, they will be attracted to each other (at least unilaterally).
So, If you can (possibly) be lovers you can't be friends. If a girl/guy wants you to be JUST friends is a polite way to dismiss you or tell you that she/he finds you unattractive.
Yes. One in particular, she was gorgeous - could have easily been a model. I fell for her pretty hard but then learned she broke up with her boyfriend to be with this other guy, and realized she only cared about money. She was able to with her looks alone. After that I had to remove her from my life, I felt like she really liked me and I knew it wasn't going well with her ex boyfriend but once I found out she was with another guy and moving in with him and redecorating everything for him with his money - I couldn't be around her anymore.
I'm freinds with several girls many of whom are just not my type. I did start to like one of them so I told her that I was starting to like her and she simply said that she was not into me. That ended that and now we are much better freinds because of it. If girls and guys are freinds and they don't tell each other that one has a crush on the other that is when it is not health.
Two of my closest friends are very attractive girls. They're single, I'm single, and there will never be anything more than friendship here.
I have never been friends with a girl that I found to be physically attractive and not at least sometime during that relationship at least CONSIDERRD or pondered about us being together. But yes I have been just friends with attractive girls.
