In Fable on the Xbox there´s gay love and gay marriage

My 13 year old son Tom and I were playing a game called Fable on the Xbox in our living room. In this game you become a character who roams a medieval world and you choose to be good or evil, you can fish, you can cook, you can buy a home and engage in commerce. Interestingly you can also find a bride and fall in love, or in this modern day fable, you can find a groom and fall in love (but you can only be a man character in this game). Tom and I were pretty surprised to learn that in this game there is gay love and gay marriage. Much to our surprise a man came towards our male character with a big heart symbolizing his homosexual attraction to us and asking us to buy him a wedding ring. We passed. As much as I am in favor of gay marriage in real life among consenting adults I am not sure that I endorse gay characters proposing to my 13 year old in Xbox games.
