My girlfriend asks why nipples are becoming larger of her?
Hi when you say getting bigger do you mean just the nipples are getting erect or the areola the area surrounding the nipples are getting bigger?
Just nipples gets erected
That can happen because of sexual arousal or also through the cold.
How old is your girl and how long has this been happening?
What is sexual arousal....and she is 25 yr old
It is happening from 4 months
Sexual arousal is the same as sexually excited like when a guy get sexually aroused if gets an erection.
Has she noticed any other changes to her breasts?
White fluid coming out of her nipples
I would advise her to go and see her doctor and get it checked out :-)
