Spice up the bedroom/sex life

I’ve been with my partner for two months now. I have body insecurity issues and I really want to start wearing lingerie but I don’t know where to start? I need to take baby steps haha.

So I have a few questions:

1. What are some lingerie styles to start off with?

2. How in the fuck can I get better at dirty talking

3. Do you have any tips for riding him? I do this thing where I roll my hips but I want to get a bit better

4. Any other sex tips/foreplay tips you might want to share?

Thankyou!!
