Submissive is seen as weak.
Just for fun I went over to the fountain of all knowledge...Wikipedia...and did a search for what they felt Submissive meant.
Submissiveness is the incidence or trait of voluntarily yielding to the will of another in an interpersonal relationship, or as a result of intimidation to some display of assertiveness or aggression by a partner. It can be found in everyday human and animal interactions.
Interesting. Let's keep reading, shall we.
In interpersonal relationships, some people prefer or are willing to adopt a submissive role in sexual activities or personal matters. The level and type of submission can vary from person to person, and from one context to another; and also is dependent on the other partner being willing to assume control in those situations. Some people can include occasional acts of submission in an otherwise conventional sex life, or adopt a submissive lifestyle.
What I like about this definition is the awareness of the range of submission that can be had in a sexual relationship. It's not all whips and chains people (though those can be a LOT of fun) and we should broaden our views of what submissiveness means in a sexual context. You can play Dom/sub games with a partner. It can spill into your day to day life...or never leave the bedroom.
The power in the Dom/sub relationship is with the sub. They are the ones who set limits (though some Doms have lines they won't cross as well) and they can halt the games as they go on.
It takes a lot of strength to give control to another person.
So what do you think?
