How Do You Feel About Love/Relationships At This Point In Your Life?

This was a forum topic I recently encountered and the following was my response:

At this point, having been married, single and everything in between, as well as seeing the experiences of people around me and reading about these things online, I have to say that I am opposed to relationships in which the two parties are living together. At least for now. I own my own house and am perfectly content being alone in it. I have absolutely no desire to live with another woman at this point (I have lived with 2 in my life).

As far as relationships that don't involve cohabitation go, I am not necessarily opposed to them but at this point in my life I don't even want that. To be honest, I have much more fun hanging out with friends/my brother than I ever did with a girlfriend/my ex wife. Really, if you take sex out of it, you have a friend, but in most cases, one that isn't as fun to be around as are your male friends since females and males are often so different (what they consider fun, the conversations you can have, etc). Of course I am generalizing here but that's the nature of the conversation.

I really believe that despite what we tell ourselves, access to sex might really be the biggest/most potent motivator for the forming of relationships. Not many relationships survive without it and guys will go to extreme lengths to put up with **** that they would NEVER take from friends and the reason for that is sexual desire- which, if you really want to deconstruct this, is simply the biological urge to procreate. I believe that alone is the basis for all of it, and everything else is  a nice little narrative constructed around it.
