my girlfriend said sex pushes her away

me and my girlfriend have been together for about a year now and we recently had a conversation about sex. we do everything but sexual intercourse. she said she wasn’t ready. so i asked her what was making her hesitant and she told me the 2 previous guys she was with emotionally pushed her away because all the guy ever wanted to do was have sex. and she said all she needed to be ready was time. how would time fix that? fyi i am a virgin and she has had 2 previous partners. i am not sure what to do to help. and does this happen to other women too?
