That's exactly what I was going to say. If someone asks me out and suggests the location, I assume that they are paying (though I will still offer). If I ask someone out, I would go out (in the same respect) with every intention of paying. When dates start becoming mutual, I don't like to split bills, either. I'll pay one time, and they'll pay the next time... They'll buy the first round, and I'll buy the next. It works out to be the same cost as splitting bills, but it doesn't have that same scrutinizing attribute of counting costs and tallying items. It's just more courteous.
In a similar situation (but different) a buddy and I started this: you pay this time, I'll get the next one. Well it was fine until I started to notice that when it was his turn to pay, we did harveys, wendys, dangerous dans, less than $20.00 and no tip. Then when it was my turn, we ate at a sit down place. For eg: I was sitting there watching the tube one night, he calls me up and says: hey, I feel like chinese, let's go...so I thought, yeah I could eat chinese. So the bill comes, it's $39 plus tip, so I pull out a $20 and start rooting for change. He (with a straight face) says: ummm it's your turn, I got it last time. I was like, "whoa dude, we had harvey's and I only had a poutine and a coke", he shrugged. I said, you at least put in the tip, he said: I don't have any money. ARRRGH. The asshole wanted chinese, knew he didn't have any money, so manipulated it so I'd pay.
I put a stop to that RIGHT away.
Not to say I'm petty or anything, but I was trying to save for a house and that $47 was my grocery budget for the week. Blown in one sitting. I'm not saying ALL women would do something like that but it's something you have to be conscious of. If I was in love with someone I'd have no problem treating her to just about everything imaginable (and have) but it does get costly if you're on a budget.
Now one thing I've heard from women is that some guys tend to think: I've paid I better get something. So maybe it's a good idea to stress you're paying your own way? Take a look at the threads here on what is cheaper? a pro or a civvie? I just want to say I don't think that if I bought dinner and a movie for a woman I expect her to F my brains out but when, as a guy, you're putting out quite a bit of money on a lot of first dates, and go home with blue balls, it is more economical to just hire a pro.
BTW: your sig pic is quite naughty. mind if I "come over" for some sugar? *eg*
