think about it this way....
you plan on getting married to someone, (someone who's obviously your kind of person, great to be with, good looking, awesome in bed etc etc)...eventually and settle down.
imagine where you've been, the people you've slept with, "just to try before you buy" typathing...
and then your going to marry this person, your standing at the alter about to say your i do's and what not...then a chick silently gets up, comes over and holds the hand of your husband to be...and then another and another..untill theres a line of say, 17 gals standing next to him.....one of the chicks says to him "why hello there! those are some pretty hefty promises your making" or "oh, what a pretty bride" "does she know about all the things you used to wisper in MY ear?"
you ever so politely wisper to him "whats going on?" "who are all these girls?" obviously theyre people he's been with....
think about all the ppl who could line up next to you on your wedding day, people you've given yourself to 'just for the fun of it'...
try to view people you meet as somebody elses future husband or wife, coz ultimately thats probably what they'll be.
it might be fun, physically, but obviously if your even considering 'moral and ethical' values or whatever then you do know its not the best thing to be doing....
there's an awesome book on this stuff called "i kissed dating goodbye" i recomend it...
but anyway, no one can tell you how to live, and thats not what im trying to do...
catchya!
