I never make the exclusive talk first. I keep my heart a good distance away. Sure, it's been years since my last LTR, but if they don't talk exclusive with me, neither will I.
Also don't move too fast, or you'll get dropped or friendzoned.
Never entertain exclusive talk unless sex has happened several times.
The first time I made love to my most recent girlfriend (versus sex) was about 10 weeks after we first had sex.
I accidentally implied I was talking about a commitment (I wasn't) and I literally saw the fear in her eyes. And lots of guys do this on the first date before ever having sex!
Five weeks later (week 15) she was the first to say "I love you" and she brought up the idea of exclusivity, saying "I love you, and I don't want to restrict you, but I don't want to think you are with other girls.." (I didn't agree to commit but neither of us has been with anyone new since).
So it goes:
1) Dating
2) Sex
3) Making Love
4) (Time)
5) She brings up commitment
6) You resist
It does NOT go:
1) On the first date he tells her she is not allowed to be with other men or else he declares her a no-good ho.
