Not that much.

Answer 3

I know that I lived with my dad and step mom.  I wasnt in contact with my mother for years.

I lived with my mother til I was 12, we talked about almost everything, She believes that openness is the key.

As an adult I found that she is very open and helpful. My step mother has never been very open, she also was raised with different feelings on what children and teens should know before they are adults.  

I know that my mother being open with me when I was 17 and 18 helped with my relationship with my boyfriend(now my husband).

If you feel confident that your mother will not get upset or stop talking to you when you want to talk about something that most parents do not ever think about talking about, like s*x with your bf, Then go for it.  

Good luck, try to be open and honest.  Start out some touchy subjects with things your friends have done and see how she reacts.
