It would depend on how it was presented. I had an ex who badgered me about it and when I finally said 'maybe' he got the creepiest gleeful look in his eyes. Then he proceeded to plan out every detail of it, even though I hadn't agreed to anything yet. Needless to say, it never happened.
At the end of the day I'm not opposed to it, but if you're making me feel uncomfortable about it then I'm just not interested.
