I am 14 and want to have sex with my girlfriend but she is not like that(as far as I know) how do I change her mind into wanting to have sex with me please answer
Just don't be a jerk about it don't force her to do anything that she doesn't want and over time she will open up
You don't change her mind. She is probably under-age, and also any coersion could be considered as (attempted) rape. You are being selfish in wanting your sexual desires satisfied by an apparently unwilling girl. Of course you want to ahve sex, but exercising self-control is part of growing up. If you cannot exercise self control now, then how are you going to cope in the future when she is unavailable? It seems like you only see her as a sexual object and not a whole person to be respected.
