I've got a male friend that I've known for several years, we share a hobby and so socialise quite a bit, usually trips to the pub with others.
Friend in question has recently become single, after quite a long-term relationship ended. I'm single, have always had a bit of a crush on friend and think it'd be worth us trying out dating. but it is clear from conversations that he sees me as one of the lads. I would like him to start noticing that I'm a single female and therefore in the potential pool of women he could date, thus laying the groundwork for me to possibly make a move in the future (i'm pretty sure any move now would be too soon and also rejected because he doesn't see me that way). I don't want to drastically change my behaviour but any suggestions on how i can get him to notice I'm female rather than just a drinking buddy.
