Do you think there is a difference between experimenting and pushing your comfort zones?
I would say there is - surely the former is exploratory; discovering preferences, senses and pleasures whereas the latter is seeing how far you can take things for the sake of it... but that is my opinion.
In relation to receiving the emotional high, one thing I have found is personally it is less related to the activity that I am performing and more to the person I am with and the situation as a whole.
There have been times I have had "vanilla" sex with somebody where for that particular night we connected physically and emotionally and it was an explosion.
Contrary there have been girls (some at the same time) who have dressed up to the 9s in lingerie then we essentially mistreated each other in the name of fun and it was disagreable to say the least
Then I have also had the flip side of both of those scenarios.
It is about finding out what you like and then doing what you both want (or an enjoyable compromise)
I wrote a
field report about some really bad but an instance of great sex that I had (see point 2). The girl wasn't perfect but for whatever reason the chemistry was awesome and we found a rythm that wasn't outright BDSM but definitely wasn't vanilla.
All I would say is go out, enjoy yourself and try not to let any social or pornographic misconceptions lead you away from what feels good
