As many stated before, I think topping from the bottom can be very harmful to a relationship, nevertheless I have caught myself from time to time falling into a behaviour that I cannot deny was topping from the bottom.
Without even thinking about it I tried to provoke a certain reaction from my former master. Still, whenever I realized what I did, it made me feel really bad.

I didnīt intentionally try to take control, still I unintentionally tried to lead my master into something I didnīt know he wanted.
I thought a lot about why I did this, and why I felt bad about it afterwards. I didnīt even try to provoke something I liked. Sometimes I felt crazy because I had the strong urge to make him do something i really didnīt like at all, to hurt me...
I think part of me was afraid at that time, afraid of my own likings and afraid of beeing hurt, afraid of beeing hurt because I got involved to quickly.And I was convinced that I would be hurt anyway so I tried to get past the hurt as quickly as I could.

If he had not felt my topping from the bottom and set it to a sudden stop by just ignoring every attempt from me, I would propably have fallen back into my previous behaviour of mistrusting every person, especially every man that came to close to me.
In retrospekt I think I was just looking for an excuse to strengthen the walls again, that were slowly breaking around me.

I have come across people who think that anybody topping from the bottom is no real submissive, people who told me that, somebody who had topped from the bottom just once should better rethink his or her role in BDSM.
Even if I am convinced that topping from the bottom is harmful to a relationship and disturbs the dynamic of said relationship, I think it is up to the couple in question to deal with it. Dom should be aware of the possibility of sub trying to top, And sub should reflect on her own behaviour some times.
Relationships are something very complex and putting blame on anybody without knowing the background is no option.

Sorry for my ramblings, this is a topic that touches something deep inside me.
