You told us your height and weight but it's not really about that, you didn't tell us your ability... I'm a girl and 5ft 5" and 8 stone... I play rugby, I'm very good, so you cant just been good for your size. It's speed, agility, movement, teamwork... But if you do also have great skill then you could maybe be a flanker? I'm too small for that. Hope I helped. Sorry if I seem like I'm criticizing. :)
Any one can play. You have the size and weight but wether you'll be good or not is another question and if you play your coach will decide what position you'll play (I use to be a second rower but got moved to wing and am now a constant winger) if we assume you have good ball handling and tackling skills than I'd say second row.
You have the height and weight for it. You also have the ability to get knocked out, break a leg or arm, or injured in some other form. Go to a field and find out what position you would fit in.
