I like you too Aphrodite--tho I keep wanting to change your name to 'Aphrodyke' just because I'm relentlessly punny.
As for being exclusive... It's a nice idea and all, but it doesn't really last a lifetime, does it? I think a relationship will work better and last longer if you're at least honest about desires of others. this, of course doesn't mean you have to act on them. But... being young and passionate and curious and uninhibited isn't exactly ideal for a strictly 'exclusive' relationship either, but none of those things are bad things. I really tend to believe in a 'sowing wild oats' ethic--except of course, no actual sowing in this day and age of readily available birth control. I could probably do it at this stage in my life, becuase I've sown a lot of oats in my day.
Boy I sound practically doddering, don't I, at this ripe old age of 23.
What I mean is, I'm pretty experienced, but am now no longer as promiscuous (I don't like using a word with such negatiove connotations, but there it is) as I used to be--actually, I seem to have turned into a serial monogamist!--and I think it's because I got a lot of it out of my system. I don't think I'd be a very happy girl now if I had never had a threesome. God, if I had never started with that stuff, I probably never woulda worked up the nerve to touch a girl on my own, and my life would be much different, and I think much less happy.
So... experimenting is good, if it's all done in the name of fun and honesty--Let the games begin!
