Marriage Romance Kids and Honesty

It always pisses me off when friends and family say, 'just wait till you are married and have kids' to which I reply 'fuck that. never' and they roll thier eyes! Everyone I know knows that I am not getting married, or having kids. In fact next year I'm having my tubes tied so I never have kids. (TMI i know, but just to let you know how serious I am.) Yes there is that .00001 percent chance Ill change my mind, but then I can help a poor kid from africa. It seems selfish to have your own flesh and blood kid, when there are so many other starving/dying kids that need homes, and families. I don't want kids, and I don't wanna get married. Now, I think if you CHOSE to get married, theres NO ecxuse as to why you would cheat. My idea of a perfect relationship is a polyamory. For those of you that don't know what that is:
'Polyamoryarticipa tion in multiple and simultaneous loving or sexual relationships'
I know what your thinking. What a slut. but no. I wouldnt be involved with everyone I know. I want a good loving relationship, like the basic living w/ the boyfriend in a nice house w/ a dog kind of relationship. But I would want freedom. Like when I am successful and have my own business (ahh, what a beautiful daydream) and I have a fucking gorgeous business partner I would want to be able to have fun once in a while, and not be worried about my boyfriend finding out. Not just me, I would want him to have his freedom also.
Ive learned my lesson. I had a relationship for 2 years with someone I loved I guess, but I didn't find out until the end of the relationship that he wanted to get married at some point in his life, and have many many kids of his own. I told myself I would make it clear what I want before I get involved in someone. No I am not willing to be flexible in this issue. The whole 'OMG! were you lookin at her ass' is not appealing to me. I don't want to be that girl, and I don't want my boyfriend to be that boyfriend.
To the next issue. Romance
So many chicks I know want their man to make them a dinner set the table with candles and roses and sip wine and talk until the wee hours of the morning about feelings. That even makes me sick. What the fuck is the deal?? Why would anyone want to do that?? Ugh. I hate romance. The whole idea... I just dont understand. What can that do for you that a hardcore sex life can't fulfill?

The other day this guy I know made a move on me, and it pissed me off. He has a girlfriend for 2 years, and he cheats on her all the time. The ones I know of count to a total of 7. His girlfriend is in such denial. Anyways the point is, he wants to be in this relationship, but lies and cheats on his girlfriend. I think it's about time we all kick each other in the ass for being so retarded, and learn to be honest and open about our ideals, feelings, and experiences. It would make the world a better, more open and honest place.
Having said that, I also think that when we meet someone the lines should be:

'Hi, I'm _______. Nice to meet you. I think your hot, and if you wanna have sex sometime, you know where I work/live.'
This would also just make things easier, instead of playing 'that game'. you know....The one where you do stupid shit to get the person to notice you. The one where you do something retarded, hoping they will say 'hey, lets go fuck' but you end up in the hospital, and without thier number.
