Best friends boyfriend

GIRLS OK SO

I’m thirteen in hear eight. My best friend thirteen too and she has a boyfriend. She’s known him for a year and four months but has been his girlfriend for about five. Their going on a date tomorrow to the movies. And they’ve made out before, a lot. But she told me that they both want to unlock their “sexual sides” a bit. As in letting their hands wonder. Apparently his hands are gonna wonder down her skirt in her undies to her butt and boobs. But she going to his dick. She told me about this Cos we super close but I’m just wondering, do you think she should be doing this? Is she too young? I asked her if she wants him to touch her and if she wants to touch him and she said yes. What should I do? Do I support her and help her when she asks or no?
