I've been having sex with a guy from work. Was a bit of flirting over text which lead to what I thought would be a one night stand. After said one night stand he messaged me "more where that came from" fast forward 6 months were still having sex. We don't have any other conversation as such. It's literally just a quick hook up. Now I've started to like this guy but I'm too scared of rejection to ask him out. Is this just sex for him or should I ask him for a drink
