Most Helpful Girl
She'll bring it up when she is ready. She knows that you are. If you ask again, she might feel pressured to "give in" which isn't nice. Let her make that decision on her own.

The LAST thing you want to do is say "Hey, honey. So do you want to have some sex?" DO NOT ASK her. By doing so, you are putting way too much pressure on her. When she is ready, she will be ready. You can not talk her into it or ask her.
What you CAN do is give hints and make an effort to set it up. Timing is everything. Plan a romantic evening with her when you know you will have lots of alone time. It doesn't have to be anything fancy. Bond with her. laugh with her. Share your feelings with her and more importantly, LISTEN TO HER. Once you get back to the place where you 2 are most comfortable, Snuggle with her, kiss her and always make eye contact with her. In the heat of the moment, whisper in her ear "I love you... and I want to make love to you". If she says she is not ready and you truly love her and are willing to wait, just accept it for what it is.
Although it may not happen that night, What will happen is that she will know that you are down and ready whenever she is... AND she will respect you for not pressuring her.
