The question/suggestion I'm most sick of hearing and having to answer:
Are you gay?
How in hell does someone not dating for long periods of time equal them being gay? Gay people(overall) date as much, if not more, no, scratch that, waaay more than straight people. I know, I've lived with a few. It's mind boggling how otherwise intelligent people can somehow come to that conclusion...
Any other questions you're sick of hearing?
