Too many variables to consider.It depends on what a woman has experienced,what her vaginal capacity is,all sorts of things.To some women, 7 is big,other will think it's average,some even small.I've had women say my dick is big(7.75 x5.5),I've had woman say it's a 'nice' size.My current gf says that to her,8 and over is really big,but she prefers 6-7 based on her own vaginal capacity,and she's experienced a really big(12") cock before.
