Whether you are in a committed relationship (ie. married, engaged, long term, etc), in serial monogamous relationships, or single, there might come a time when you consider or maybe have considered the ever infamous No Strings Attached relationship. It seems to have become more common or normal rather than taboo in society today. No strings attached or friends with benefits, whatever you want to call it, is simply a way of saying "I will be with you when I need you, but will not be there when you want or need me". Let's be honest here. No strings attached is not about anyone else but YOU. Yes, I agree that both parties have agreed on this arrangement so why should it be a big deal? It is a a big deal because this arrangement has more impact on you than you really think.
Consider this: each time you have great sex or a pleasurable time with someone, your mind creates a connection. Overtime, that connection is like an invisible string that connects you with that person. This is how mothers and fathers bond with babies and this is why babies cry when they have a need and parents are not present. For adults, we don't have such an apparent need for others because for the most part, we are capable of taking care of ourselves. However we never get rid of that need for connection. Because human connection is what kept us alive and helped us grow when we could not help ourselves. Human connection is pleasurable. Of course, I must say I'm referring to most people with the exception of people who have anti-social personality (which is totally a different topic).
Please don't misunderstand, I'm not here to say no strings attached relationships cannot work out or that it's a bad thing. To each his/her own. But do understand, that the no strings attached concept actually does creates strings between you and others (just watch the movie No Strings Attached). So tread carefully when you venture down this road or you might trip over something.
