Assuming no moral compunctions, how long does it generally take from the first date to proceed to:
1) The first kiss?
2) Fooling around?
3) Other non-intercourse sex?
4) Intercourse sex?
Are there any other (sexual) 'stages' of a (sexual) relationship?


Sometimes they happen all in one evening. Sometimes they never happen. Human behaviour is not governed by formulae.
Depends. Generally the first or second date assuming this is a person known to me...No one night stands for me; if it does not work out between us we part as friends.
Just meeting a man for the first time? Second or third date. This is obviously assuming he is someone I wish to be sexually involved with. I never went for the "week or two" rule.
Date 1 = chatting to see if there's chemistry.
Date 2 = the road test to see how well he handles the curves - my curves.
Date 2 can immediately follow Date 1 if time and interest allow.
The answers can also be age specific.
Body language plays an important part in determining how a man should proceed. For example, she can end the first date with a comment that she enjoyed the evening and hopes he will call soon. Second, if she lingers at the front door and looks expectantly into his eyes, then most likely she is anticipating a good night kiss.
If you are a teen with limited or no dating experience, I would not be rushing to have sex and would take lots of time (read: weeks) exploring each other's sexuality. Kids nowadays seem to miss the importance of all that making out in their rush for nearly instant gratification. Spend lots of time getting to know each other, becoming more and more intimate and building anticipation as well as sexual tension with each session. When you get to the Foreplay stage that follows Necking, Petting, and, Heavy Petting, the orgasms and the intimacy will be much more intense.
Please read the articles on dating, kissing, and making out listed in the Index.
Unless there you are having recreational sex, I see no hurry to have intercourse. Orgasms resulting from Foreplay activities are much more intense. Intercourse has more to do with intimacy and joining the psyches and should come when a couple achieves a deeper more intimate relationship. So, there's sex for sex sake, and when it is saved for more meaningful demonstrations.
Thanks for all the answers!
Being 26 year of age, I am not a teenager, but it is indeed true that I do not have any experience dating whatsoever. Nor do I have any dates lined up, so this is just out of personal interest as to what is 'standard practice'. It might have some personal relevance if I do go on a date some time in the future, though I realize that as somebody inexperienced I would definitely take things much slower than whatever the 'standard practice' is.
