I was going to throw out 17, but thought it would be way under, you probably got that many in the latest purchase thread. I also thought if I went too high, you wouldn't answer.

Don't worry though, twinkle toes, I got a fool proof fag test for ya:

You like to eat pussy?

Well that settles that. If you fully love the vagina, you enjoy eating it. If not, well then you are probably a top in waiting.

Goes the other way too. I think if a chick doesn't fully embrace the dick and enjoy it in her mouth, then she doesn't really like guys, just trained her self to tolerate them so she doesn't have to be a dyke.

P.S. There is one potential flaw in the question. If the desire to give oral waned in conjunction with a significant other turning into a disgusting pig, male or female, then that is understandable.
