Adventurous sex

So ladies, I need help! My man is a lot more adventurous than I am. Don’t get me wrong I LOVE the idea of having sex in the car or on the beach ect but I have the worst anxiety and I get paranoid a lot. We are having a baby soon and after we have him I really wanna start spicing things up in our sex life. It’s always the same thing in the bed and what not. Only adventure with sex we had was probably sex around the house and shower but that’s it. I wanna do it in the car or on the beach or in the woods (obviously where there isn’t people). I just want some ideas on how to spice things up I need help how to not be so paranoid! We are only in our 20’s and I really want to do some fun exciting things before we have more kids and grow up
