This is a big one, and I believe that many modern guys do try to understand it. I think that as men get older they become a bit more aware of it and learn to interpret their own gut feelings, though they might find it difficult to follow those feelings.
Chemistry is not about a twitch in the nether regions, though that can be a part of it! It is about feeling that you really want to know more about the other person, that she(/he) excites and interests you and you want to meet again as soon as possible and develop communication. You have to meet to find out if it’s there. My view is that if it isn’t there at first meeting then it will not develop later. If you don’t recognise it then try and watch for the symptoms!
Sometimes you find that it is mentioned explicitly in the narrative (free format) part of the profile, where it is arguably more important than in a drop-down box, as the lady has put it in without prompting.
Ladies are much more tuned in to chemistry than men, and consequently react in ways which we cannot always understand – now there’s a revelation!
Women are much more adept at reading body language – men have to consciously work at interpreting it, whereas its almost subconscious with females. Ok, I’ve moved off online profiles into other interesting areas.
So, if you don’t know what chemistry is then start learning.
Can you read body language? Want to know more? Try this Peoplewatching: The Desmond Morris Guide to Body Language - Desmond Morris is a renowned author (do you remember "The Naked Ape" - it caused a stir when released). He gets down to what's really underneath our skins. This book is also useful in a professional context, helping to read customers, colleagues and others.
