Do you masturbate (what a question)? Next time that you do, see how many fingers you can comfortably get inside. If three are kinda tight, you are of average size (down there) and need to probably NOT seek out "large" men right away. If three fingers are really no problem, you might be a candidate for something "big". Your friends are most likely talking smack, big dicks are not very common and most young girls do not have a proper frame of reference to gauge whether or not someone is "large". Call your friends out on their bullshit and try to get some peace. You should be going for the guy that treats you nice, makes you laugh, is attractive, and has atleast some of the qualities of a gentleman. Go for the big dicks only after you have a little experience under your belt.
