Different for every guy I would think. Maybe avoid talking about marriage and kids within the first few dates maybe if you are doing that.

Tell me your qualifications. What do you like to do for fun. What do you do for a living. Are you aiming for guys that are perhaps too high up for you? I'm not going to lie a lot of people tend to have an image of someone that is perhaps too good to be true. Me included. You've said you don't want a fat guy but you yourself don't like to exercise? Seems a bit unfair to expect that of others when you can't expect it of yourself. I'm not saying to go for a fat guy or someone you don't find desirable because a person shouldn't settle.

You get what you put into it. Try not to seem desperate.
