How to stop Sims 3 from shoving homosexual relationships at me.

This attraction moodlet that came with the seasons expansion is really annoying me too,i havent had two sims of the same gender attracted to each other yet but my married couples sometimes meet new sims they want to just befriend while out at the park and the moodlet will pop up that they are attracted to each other and they get wants to kiss a certain sim they just met and also keep getting love letters sent to them in the mail from these same sims wanting to go out on a date and just openly encouraging my sims to cheat. :roll:
