Your balls shouldn't be that shrunk bro. Make sure ur still using them in some regard (ie. having sex). They really shouldn't be that drastically smaller though. Ask your girl what she thinks and if its that noticeable because that's all that really matters. If girls have a problem with their size then that's not good, but you fuck with your dick, not your balls, so if a girl is complaining about your balls, then they are really small and something is up for sure...
