I understand what you mean, but you are slipping into presumption. You are placing your own thoughts for those of God, this is what has led to so many splinter groups and the whole Protestant revolution. Basically you are saying that because YOU don't think it is wrong, or that because YOU want to justify it, then YOU must be correct. You are placing yourself as God when you do this. I know that is not your intent, but that is the outcome. For instance, if love was the prerequisite for something being Good, then a alcoholic that LOVES booze can justify that "God created it, so it must be good" or a drug addict saying the same thing about drugs. Where do you draw the line then? Is nothing a sin? How about people that want to feel that wonderful feeling to fall in love with 10 or 20 different people a year? Is that also justified? God created us with sexual desires, and he gave us the Sacrament of Marriage to live out our lives. God created Sexual emotions to draw us to our spouse and create a special bond between us in which to live our our vocation of marriage. God did not Create it just so that we could "Feel Good" but this is getting trampled in our "Me" centered society. God gave us all we need to be happy, and he gave us the Sacraments to use what he gave us in a happy, productive way. God also gave us the Catholic Church to guide us, what other purpose does the Church have? I suggest you pray about this and don't throw out God's Church lightly, for the Devil is very tricky. Good Luck and God Bless!
