I feel like I'm walking a thin line on the "we are happy to pay for this" BUT "these are really expensive so please please take care of them" issue. It's tricky.
I do feel lucky and blessed to be able to spend so much money on certain things and I never want to her to feel guilty about it, at the same time, she's 13 and left her $98 swim suit on the bath room floor twice last week. It's age appropriate, and I try not to nag her more/differently than I do her sister for leaving her $14 suit on the floor. I'd love to buy one on clearance this fall for her, but I really don't know what size she'll be next spring so it seems a bit pointless.
I'm excited to have so many more stores and options to check out with her.
I do talk about relationships, sex, etc. When we watch movies together, we talk about the characters and what she thinks of their choices, whether the movie seems realistic etc. I read some of the same books she reads and those are often spring points for conversations too.
I also bought a couple of very open books on puberty related issues and have them where the kids can look things up when they want to. She has access to solid information and knows that the choices she makes are her own, and that we will always love and support her.
One of the things that I've tried to teach my girls is that sex can change the way you feel about a person, making the emotions more intense, and as painful as it is when a relationship ends, it can be even worse when they relationship was sexual.
I've let them know that I have their insurance cards and if they ever want to go on the pill or whatever, they can just say so. I've shown them where condems are in stores, how inexpensive they are. None the less, I've encourage them to wait until they are adults and to be very selective. It's a thin line. Sex is a natural part of life, and yet I don't think anyone is best off being ruled by their whims. I think sex is best as part of a solid relationship where you care about the whole person, and you know that they care about you as a whole person.
Still, we don't get to make those choices for our teens. What ever choices she makes, I want to stay as safe as possible.
