OED v. 2 under 35 experiences

[Shannon]

It appears to be. Two more things that came to my mind today: the belief that by having sex with a woman I am somehow hurting her, and another thing I just remembered: my dad used to tell me every now and again when I was younger something like, "keep in mind that after you sleep with a woman she will believe she now owns you", which, while actually in some contexts could be considered pretty solid advice, is not entirely true, is it? Also, nobody likes being "owned". So maybe it's time to disregard this little piece of advice, haha.

Also consider that a man who properly owns himself does not necessarily care if a woman decides she thinks she "owns" him.  I don't advocate for carelessness, but being controlled simply by someone else deciding that "because X, I now own you" is ridiculous.  A man who owns himself only abdicates that by willing, intentional choice.  And if you did not make that choice, then someone else who assumes that they own you because something happened is sadly mistaken, and will have to deal with that fact.  It is not your problem.

One of the biggest issues I see with relationships is that people don't communicate clearly, in the beginning or during a relationship.  They tend to have beliefs that they simply assume are universally true and accepted by everyone else.  If she and you have sex and you haven't discussed what that does and does not mean, then you're both at fault, and that discussion needs to take place.  But regardless, making assumptions like ownership as a result of sex, or some sort of relationship or whatever is a potential point of conflict that results from poor communication.

In other words, don't let her assume, and don't feel beholden to her if she does.  This goes for women too.  Communicate, and set boundaries.  

Women who do this sort of thing will get very upset if you don't conform to their assumptions and power plays, but as your own man and your own owner, you are free to do as you please, and she is going to deal with it.  The same would be true in the other direction.  You must agree to these things, not let people control you via assumptions and guilt trips.
