LMAO, I am joking, of course! I wanted to only post ^, but then again, I think that some people might not get the sarcasm since it's typed-out and you guys don't really know my sense of humor at all! But I will hide this in the spoiler to incite a bit more dubious shock-value XD. Also, not a put-down on religion, just some social commentary on the, what I find to be, hilarious undertones of hypocritical "radical" religious philosophies; I, myself, am Christian.
Okay, now my pertinent thoughts. For me, I just go for the one mode, which is relationship-mode, but it is actually workable for others to have unattached sex with someone, but also be open to a relationship if the opportunity presented itself. But both modes cannot be running at the same time.
For example, if you go to a bar or party and have a one-night stand, I wouldn't suggest pursuing a relationship out of it - just stay in "unattached-mode" with that person. However, you may talk to a friend that suggests a date for you, and so you go on it, or you have a friend that you spend time with and you want to pursue a relationship. I would say at this point, with this person you should go into "relationship-mode". Not spending the night at their place after the vary first date, and having a commitment. And if you don't want to further anything with that person, you can go back into "unattached-mode" after expressing this thought to the person you were dating. If you still want to date (even if it is just a premature connection), I would say stay in "attached-mode," for as long as you want to pursue that relationship, but not hooking up with others on the side. (I am talking about the general "you", not you personally, haha)
But these are not right or wrongs, they're just what I think would be the ideal way to handle the situation; I have thought of doing this myself, but I guess it's a personal sexual preference, not necessarily a moral, that I apprehend intimacy with someone I don't know, or do not intend to be romantic with. I swear I would be one of those people that would seem really clingy, and be like," hey want to get something to eat, or hang-out", after a one-night stand. I am only equipped to be a one-mode type person. I don't really think though that any person should have both modes on at the same time, but should be able to access either mode depending on their current circumstances, one at a time.
