First time at a sex store

Hey! So my boyfriend and I have been wanting to try new things and we are planning on going into a sex store for the first time together, does anyone recommend anything new we could try? Or a good brand of lube ? As well as I just turned 18 this year and I look younger than I am do they check my id? It’s a dumb question but I’m nervous to go in but also excited, so I’m trying to be informed on anything beforehand
