coconuts - it is from the rules, yes, but it also seems to be anecdotally true from these threads. And from my experience - it's human nature that for both men and women , insecurity seems to have the Groucho Marx effect - that you wouldn't want to be part of a club that would accept you as a member.
I've been on dates where I've been wondering whether to ask them out for a second date and they've asked me out first - and it makes them seem a little needy. It makes me start thinking I can do better if I have to pursue someone
It is, of course, utter bollocks. I know that. I'm intelligent enough to realise there is some fucked up psychology going on in my head, and people should be able to openly and honestly express their preferences regardless of gender.
Having said that, it still happens and it puts me off them just a smidgen.
