At what stage in a new relationship would you 'discuss' sex? I read a lot on here about talking about sex before it happens and, to be honest, aside from 'flirting', I've never discussed it with anyone I don't think! Not because I am uncomfortable about it but because I just don't know how to bring it up 
I've met someone new and, whilst we're not at that stage yet, I'm not sure at what stage it should come up. Or what to say.
I'd really like to do it 'properly' this time.
