True. There is something exciting about the thought of being "forced", or as I've seen mentioned on here, consensual non-consent.

That being said, if something is on my hard limits list, it's there for a reason. I think once a relationship is built, pushing limits or exploring soft limits is fine. You want to make a sub uncomfortable, sure. But, and I'll use something banal so I dont offend anyone's fetishes, if worshipping boots/feet was on my hard limits list and I was made to do, I wouldn't go back to see that Domme. If it's on my hard limits list it is likely because it is a huge turn off for me.

It seems to me a session is better when both parties are enjoying it. The moans, groans, evil laughter, sadistic smiles, etc. heighten the whole experience. If I were a top, seeing a sub gag (out of revulsion) or looking completely disgusted would not be a turn on and not make me want to continue that activity.
