What have you learned from the experience of dating?

So who's gonna share their equipment? [:tongueout]

How long should a person wait after the date to contact the party? Usually there is a follow-up text or phone call about what a nice time one had but when do you actually set up another date? (Assuming one wants to date the person again!).

Curious as to what folks who have sex with men expect early on in a (specifically) sexual relationship; do you find that you have certain ideas about what a mans sex drive should be, et cetera?

My observation of internet dating has been that while you can post very specific interests, desires, and specifications, you will receive loads of replies from people who are very obviously not suitable. How can you discourage these people? It would be nice to have some sort of filter.
