i have always known that i am submissive, despite having 'professionally ' dominated others on a couple of occasions. Those experiences backed up the feelings that i already had about which side of the whip i should be on. Mainly because i doubt i was very convincing.... But i have to say, i learnt lots from it. So, even if your not sure, so what? If you explore a bit, and take the 'wrong' path for a little while you can only learn from it. And if you go down one side and end up thinking, oh this isn't for me, as was mentioned before, you can change! You don't have to stick with it!
