Did anyone have sex on their first or second date?

Did anyone have sex on their first or second date? If so do you think it's a good idea? How was the sex? Did you date the guy or are you still with him? I've thought it can be useful to see how you connect sexually with a guy before having a relationship and then later finding out you have wildly differing sex drives or there is a problem such as him having a small penis. It's also nice to 'try before you buy' and see how good he is in bed and if he knows how to pleasure a woman and use his dick.
