being a silent type has its up's and down's
but everything is relative...you might be considered quiet compared to some guy who yaps all-day non-stop.
it's true ones who talk a lot tend to make more friends however this doesn't necessarily mean they're attracting girls, i know a lot of guys who talk a lot and they chat with many girls, but most of these girls see these guys as their 'little brother'
but you shouldn't be all silent and sit in the corner like some social-reject. you need to talk when needed but do not appear as a light-weight (who talks a lot and lacks masculinity)
its women's job to talk and men's job to show action
just a thought
