Is my sister's friend pressuring her to have sex?

right now I just turned 14 but my 19 year old sisters 18 year old friend anna just had sex and I want to know if she is tring to pressure my sister into having sex.She says things like how good it feels or other things what can I do to help my sister when she wont believe me about annas peer pressure?

This is not a pressure, 18-19 yo girls may tell each other their love experiences. Your 19 yo sister is matured enough to make s*x if she wants. This is not your business, but if you listen their stories you may learn a lot for your later life.

It may be pressure it may not be. Your sister is old enough to make her own decisions in sex, love or whatever. Her friend may tell her about her sex life and all that other stuff but ultimately the decision is hers. Talk to her, and hopefully she will decide what is right for her.
