When I go on a first date I always insist that I pay for my half. It's my way of ensuring no emotional blackmail at the end of the evening in that I won't sleep witha guy or even kiss him, just because he's spent money on me. If I want to at the end of the evening I will, otherwise I can walk away without any guilt that he's shelled out 50 bucks on dinner and a movie etc.
If things go further I'll usually go for he pays for a date, and I'll get the next one, but only after I know I'm interested. I just hate the idea that getting to know a guy means him spending his money on me... but a few have said I'm acting too butch feminist... any thoughts?
