I have never denied it isnt an experience, and one which should be experienced, and that the ideal 1 person, 1 partner is quite a romanticist ideal and in reality is not really viable in reality, but you seem to have missed my point here. I am stating that there is a mentality within relationships nowdays with this thinking OF things not lasting, of things ending, and as such isnt there then such a mentality which is not only defeatist but reduces the relationship to nothing more than an "experience." Again should we rename all relationships to convenient partners with which we can experience things? I find it somewhat sickening to hear dating, going-out, and all the assorted 'relationships' within their context today, as they are hollow words, and should rather be switched to 'fuck buddy for the next few months' or 'im using you to get to your best friend'
The mentality is really what im after here, rather than the act itself, i will give that in this contemporary world there really is a fantasy to be able to say you found your first and only.
Your third point is somewhat confusing, they are doing it for the experience, and that they shouldnt get deeply involved, but i ask, isnt that the purpose of being in a relationship with someone else? How are we to learn from inadequate lessons?
And the censorship, well i have no idea what we are talking about there, are you suggesting that teenagers nowdays would find such a practice of experiencing a relationship in which we are exposed to its true form bad? If so, then the majority of relationships, as you say, are merely experiences of immature, shallow conveniences.
